Now that Computex is on, chances of AMD having a Titan beater diminish every day we don't hear something from them, imo.
AMD - "We're going to release our info on June 16 with PCGamer."
GPU Gamers - "Nvidia released a card on Jun 1st. If AMD doesn't release something by June 2nd, it means their card is horrendous!"
AMD - "We said months ago it comes out on June 16th!"
GPU Gamers - "No care, if you don't have something for us June 2nd after the GTX 980 Ti came out your card must suck. Oh, and if you release your card now on June 2nd the way we ask, your card is a reaction to the GTX 980 Ti's card release, and therefore more suck since you felt pressured to release your card the day after the Gtx 980 Ti."
Their schedule is to launch at E3. I do think it would make sense to leak something if they have a good card, though.
I predict that they will launch Carrizo and tease Fiji in the stupid fail-at-marketing way that only AMD can do so well.
This is AMD, it makes SENSE to leak something I agree with you.
However, can we really know what happens in the marketing minds there at AMD?
