Developer Jonathon Blow has implied that there is a possibility of Braid making its way to the PlayStation 3 console.
He commented, that it certainly is a possibility but depends on whether Sony is interested in bringing it over to their platform.
To quote: First off, developer Jonathon Blow lets us know that the PC version of Braid should be available between February and March next year. This is to let the game have some space and avoid the crowded Christmas market.
Secondly, he's in talks to develop a native-Mac version of the game, so you Apple folks won't be left out.
Finally, although there are no plans for other platform releases in the near future, a later PlayStation 3 version is possible. Jonathon Blow comments;
"[As] I've mentioned before, a PS3 version a little later on remains a possibility (though again, this depends on whether Sony is interested in the game)." More PlayStation 3 News...
