Braid creator Jonathan Blow has explained why his next game, The Witness, won't be coming to PS3 or Xbox 360: it's because both platforms are too old.

"We like 360 and PS3, but their specifications are over five years old now, and that's a lot in computer years," Blow told Edge. "The kind of tricks we'd have to perform to get this game working on those platforms are such a lot of work that to port it over at this point is just not worth it for us.

"The budget of this game we would hope to make back through Steam and iOS, plus I would like to make a profit. But breaking even is most important as it allows me to keep making games, and I can do that without consoles. Maybe this time next year I'll be singing a different tune because I found out I was wrong, but I don't think so."

But while Blow's mind seems to be fairly set with regards to current-gen home consoles, he sounds like he's still open to the idea of reaching other platforms:

"By the time this game comes out in a year or more, we might be on an iPad 4. We do have to compress the game for that platform, but we don't have to do the certification stuff we would have to on consoles, so we can live with doing just one of those giant tasks. And I like this as an iPad game. It's a natural thing. But we'll see how that plays out."
