I'm thinking of saying goodbye too CS6 and starting out with CC.
I've seen that the tablet application is also included in this package and for me this could me very usefull.
The only problems I have found on the Adobe website is that they're speaking of 12 megapixels and not about editting in RAW.
Now is the question... Can you use the application with a 18 Megapixel photo and in RAW?
RAW? No. Compatible formats are JPEG, PNG, PSD and PSDX (PS Touch's own file format).
Wouldn't be surprised to see some sort of "RAW file syncing" like Adobe just did with Lightroom on mobile, though.
12 Megapixels is correct...for import, anyway. Oddly enough, I think you can create a 4096 by 4096 pixel project, which is a little bigger than 12 Megas.
