I was having a discussion like this with my mac gamer friends, and the general consensus is that Apple will not try to push into the console market.
Apple markets their product as a lifestyle, which doesn't include gaming. If they were to make a console it would alienate all their current Mac fans and they would need to generate an entirely new set of fans.
Also, Apple doesn't like to sell cheap. They like their hardware powerful, reliable, and expensive, which isn't going to work next gen.
As for the other competitors, I think Sony and MS are going to take a lesson from the Wii and release cheaper consoles with innovative controls. Also, Nintendo is going to do something crazy that isn't motion control.
Wii has more 20 million sellers than PS3 has 5 million sellers.
