But, they've given the SDK already to people in an Alpha, surely other people wanted it but they haven't given it to everyone...... thus the only logical conclusion is they aren't planning to release the SDK for everyone.... for monetary reasons which make no sense. At least that is the impression some people are giving
Ue3 will have likely many games still in development for it, and I would presume many more games will come out in UE3 than UE4 in the next year or two before the majority of games start coming out on UE4.
AMD not going to release a public Mantle SDK, yeah, sure, I mean AMD have said they will, everyone expects them to, it makes no sense to not do it, but the resident AMD hater says they won't so he's probably more accurate than everyone else, sure.
Alpha's/beta's and working with a limited group of people is apparently lost on Frosty, it's better for AMD to just invite 500 dev's on board tomorrow, and have 500 guys giving feed back on the same bugs over and over again. That is how all software is developed, it's never released to small groups first until they hit another milestone, then release it to more, till another milestone, then release it publicly. Oh wait, that IS how the industry has always worked for most software........
