A few things I noticed:
- External micro SD detects in storage including size of card, freespace, etc but won't let me do anything beyond that. Titanium Backup won't detect the card at all. I can write files to it on Windows 7 but it won't let me read files from it.
- Same sound issue as on the 4.3 ROMs (up pitch audio). Tested with YouTube.
- Other stuff outside of camera and NFC seem to work just fine from testing.
