it's about controlling the message, but leaks or not how well would reveal had gone if they said custom upclocked jaguar, with some Polaris features on stage?To me the whole DF thing felt more like avoiding the rumour mongering period where the console hardcore hunts for the slightest (NDA) details with a lot toxic speculation based on half assed leaks. Compared to Feb-Aug 2013, 2017 looks like an idyllic time.
last e3 they already gave core and flop count so they would've had to say either on stage or right after.
doing deep dive after, damage would been done. First impressions and all that.
