When I Select "Edit in Photoshop," Lightroom sends a JPG instead of a PSD or TIFF

Question

To get started, I'm on LR 5.2RC and Photoshop CS6.  All software is up to date and both ACR's are the same at 8.2.  And my source files are all JPEG's.
When I select the "Edit in Adobe Photoshop CS6" option on an image, I get the proper "What to Edit" pop-up window and have the option to edit a copy with LR adjustments, edit a copy, or edit original.  My problem is that no matter what option I choose, LR will make a copy of the image as a JPG (rather than a PSD) and send that to Photoshop. 
I've gone to LR preferences and tried changing the file format option to TIFF to see if that would work, but same problem...LR still makes a JPG and sends that to PS.
Any thoughts on how to fix this?

It sounds to me as if you may be selecting a user-saved external editing preset rather than the built-in Edit in PS option.
PSD / TIFF / JPG are the filetype options for the former, but the latter only allows PSD / TIFF.
If so, such a preset includes a selection of file format, bit depth and colourspace that may differ from the selection seen in the upper part of the External Editing dialog. This preset may not currently appear in the lower part of this dialog either.
The lower part of this dialog is used as a workbench for managing as many editing setup options as you like. These can be named and saved as a preset, or recalled for adjustment and re-saving (update), using the "Preset:" menu.
The "Edit in PS" context menu when used within e.g. Develop, will show any named editing presets you have made below (but only if successfully auto-configured) a built-in "Edit in PS" option which is controlled by the upper part of the dialog mentioned above. The built-in option is not dependent on any user preset. One indication that LR has not properly configured itself for the presence of your PS, is if the additional options (Panorama, HDR, as Layers) do not appear when you highlight more than one image and select Edit in...
This configuration apparently can be "broken" by uninstalling an earlier version of PS, which removes some system configuration that the later PS would be relying on for its LR partnering. Or I guess there may be other causes.
IIRC, usually the answer to that, is a "repair" reinstall of PS - which LR should then properly recognise.
One comment: if PS and LR are configured as "aligned" versions, it is normal to meanwhile see the filetype of the source image file as the document window title within your PS session - even if that source file is Raw, which is not something you can in fact edit using PS. This rather misleading IMO document title, collapses down to an actual proper filename only once the document has been Saved from PS - or if you close PS without saving, no actual file is made at all.
Only then is LR's suggestion of filetype, filename and saving location (as configured in LR's external editing options) implemented for real - though if you instead select Save As, those suggestions can all be overridden by the user, and LR should still auto-import the resulting brand new file.
OTOH, if you are using any external editing preset or if ACR+LR versions are not aligned, the file you see inside PS is always one which has already been saved (and already auto-imported to LR).
