Consoles aren't even announced yet lol. I don't think anybody will dominate. The gaming industry has changed since the Ps2 days.
I think the order will be this
1. Nintendo
2. Sony
3. Microsoft
Until Nintendo actually loses, they are the more successful console maker, even without counting handhelds. I think Sony and Microsoft will be close but Sony learns it's mistake of horrible launch prices/no games and takes the momentum.
