Is Verizon going to offer the 32GB and/or 64GB models of the Galaxy S 4?

Question

I have been waiting for months for information about this phone.  It has come out incrementally in very small bites and, slowest and most grudgingly of all, from Verizon.  Now, finally, Verizon has offered pre-order of the 16GB model.  I don't want the 16GB model.  I want, at least, the 32GB.  If that had been offered, I'd have pre-ordered today.  Now, I don't know what to do. 
The "sales associate" I spoke with said she had no information concerning the 32GB model other than it is not offered now.  Will it ever be offered?  She has no information about that. 
This is to be my first smartphone.  So, it is my first experience with the whole smartphone buying experience.  I am totally disgusted with the entire experience.  I'm tired of Googling every day for any scrap of information.  I'm tired of the stupid game the provider companies play with their customers.  Do they think they gin up interest and therefore increase sales by withholding information and leaving everyone interested to speculate amongst themselves about simple questions like which carriers are going to offer a phone, when each carrier might offer it, and when and if the different available models will be offered? 
I am not among the demographic groups that find it important to be the first to own a new device, I have only been anxious because I have finally decided it's past time to join the smartphone revolution and this seems like the best one to get.  However, you can only keep someone on the edge of anticipation so long before that anticipation deflates and I guess that's what has happened to me.  Today I reached the "screw it" point.  I have a perfectly good old LG that has served me well as a basic phone and I have an iPod Touch that does everything else I need, for now, with unlimited free data, so what's my hurry anyway?
Plus, in the course of searching for information on these forums, today, I discovered that there appears to be a long-term problem with Verizon and Samsung phones in the basic reception department.  While I love the idea of a pocket computer, I still primarily care about having a functional phone. 
I realize that nowadays, with these super giant companies, individual customers are invisible and 100% powerless.  Verizon doesn't care what even large blocks of customers think.  Oh, the arrogance...
Thanks for nothing Verizon.  Keep your **** secrets.  I'm moving on to other interests.
(Apologies to forum members--I know Verizon doesn't read here or care, but I can't get through to them and I had to vent somewhere.  Also, if someone could answer my question, I'd be really grateful.  Unfortunately I doubt that anyone can.)

As I understand it, the 64GB S4 is exclusive to AT&T - at least, for now. Sprint and T-Mobile don't have that either.
Sprint's pre-ordering for the S4 is closed until tomorrow. ("Sorry, we're out of stock. PRE-ORDER CLOSED - CHECK BACK ON 4/27") I don't know if that means they haven't started yet or ran out of the first pre-order stock. Sprint is only offering the 16GB model on the web site. On their web store, AT&T is only offering the 16GB model. They've already announced the 32 and 64GB models, but they aren't available via pre-order. T-Mobile isn't giving out any details about their S4 yet. They are just taking names.
This may just be a manufacturing choice. It may be that Samsung's S3 sales were overwhelmingly skewed to the low-end model, so they are making mostly the same on the first runs of the S4. As the production of the 32GB model ramps up, we may see it offered as well. I also wouldn't be surprised if the higher capacity models are only available in stores in a ploy to get customers in front of a representative so they can be upsold/crosssold accessories, insurance, etc. It makes sense in that if you are willing to pay $50 more to get a part that costs $2 more to manufacture, you probably have money for other things.
As far as the expansion slot, I'm somewhat afraid of it. I originally heard this on a podcast and have been able to partially confirm it. The NAND (aka flash) memory used in devices like this is binned according to how many write cycles it can perform before failing. (Reading doesn't wear it out.) The highest quality is being used in solid state disk drives (SSD drives) since a lot of writing is expected. Within those, NAND is binned for enterprise, pro and consumer models. The next quality bin is used for devices like phones, cameras (internal memory), and tablets, where a lot of write cycles are expected, but not quite the level of those used for SSDs. For both of the previous uses, the memory is not user replaceable if it fails so reliability is important. After that is a bin used for USB drives. It fails often by comparison, but is simple to replace - buy a new one. At the very bottom, is the bin used for SD, mini-SD, micro-SD card, Compact Flash and the like. Basically, those can be expected to fail. They are also easy to replace - with new ones. The recommendation was to either use them as semi-permanent storage by writing to them very sparingly (e.g, once) or never put anything on them you don't have a copy of somewhere else.
