I don't understand the "drama" people are getting out of this comment.
I see his point through a game's developer point of view. Not one of PR, shareholder, or hardware manufactorer, etc.
I imagine that if you are making a game and you want the most amount of people to experience it, the ideal scenario is to have the least amount of resistance to make that happen. Resistance like having to deal with multiple companies, optmizing for different APIs, different hardware limitations, certifications, etc. Some of those are limitations that must bleed into the designing process of a videogame early on. It must be annoying having so much ambition and cool ideas, but having to cut them short many times, because of those limitations that eat away budget and time, complicating things even further, because they don't work alone and have to answer to other people with other priorities within their companies and probably even outside (contracts and whatnot).
It's just wishful thinking of someone who makes games. Nothing more. He's not out to eliminate your favourite gaming platform...
