So we basically got nothing on Scarlet.
We got largely what we should have expected. Confirmation of SSD, Navi, and Zen 2. With a bonus reference to GDDR 6.
Frankly, tipping their hand with anything more would likely not have been a wise move unless they were absolutely positive Sony couldn't trump the announcement, and at this point I think nobody is certain of anything regarding their competition. So it remains a careful dance of revealing just a little bit at a time to control the message as much as possible.
I actually thought the press conference wasn't bad. I'm likely to jump in to play the Xbox One titles I missed if they can roll out just a few more titles of interest for this coming generation as well ... but no, there was no knockout blow delivered and the likelihood of doing so was always low. I hope Halo 5 delivers in the story department but frankly, it looked like a solid current generation title rather than something amazing and new. Glimpses of interesting lighting moments, perhaps, but nothing really groundbreaking.
Next year will be when we see the stakes get raised to try to sell the imminent launches. Until then we will get a very slow drip of information sufficient only to fuel pointless sniping between factions.
