MacPro 6,1 (late 2013): Bootcamp issue and Awake from sleep failure

Question

Hi there
I finally got the new MacPro 6,1 and tried to install a Bootcamp Partition fresh out of the Box. I used a Win8 and Win8.1 setup from USB Stick and the procedure worked up to the point when Windows Setup tries to update the boot configuration of the MacPro.
I searched the web and found many threads and hints, reported from Customers of the Macbook Pro Late 2013, who had the same issue:

Finally i found that also other Customers of the new MacPro 6,1 run into the same problem:

The trick, formating the prepared partition from the Bootcamp Assistent as ExFat, before reformating it as NTFS inside the Windows Setup doesn't work on the MacPro.
In addition to this problems I also registered serious problems with the Wakeup from Sleep of MacOS 10.9.1 with the MacPro.
When I set the System to sleep and wait longer than some minutes, the system doesn't wakeup if I press a key or click the mouse. I tried with USB and Wireless Keyboard/Mouse. Only pressing the Powerbutton wakes the system up again.
For me it sounds a little bit like the problems also found on other Hardware:

I searched the Support Downloads and tried to install the Firmware-Update (http://support.apple.com/kb/DL1714) but it says that my System can't use this Update. So i think my MacPro has it already installed?!? The Systemprofiler doesn't really helped finding out the right Version informations.
Hope Apple will release a Firmware Update or somebody knows a workaround?!?
Kind regards,
Frank
