One of the question marks is open now, about the RAM.
I have CDO. It's like OCD except the letters are in alphabetical order, as they should be.
So 6 question marks...My guesses (in no specific order):
1. 1 Gig Ram
2. 1Ghz Processor
3. 4G LTE
4. Direct Print
6. 4.3" qhd Screen
I replied to a couple peoples comments then realized the futility in my efforts and gave up.
Knowing everything a head of time makes most of these big PR moves a little depressing.
