I've said for a long time PS3 would but it seems less likely by the day.
It depends on a lot of things now..
- When it will be discontinued (obviously)
- How many more exclusives its going to get
- How long the 360 remains on the market
- If its going to get any sales from China
- How much more they can cut the price
I'm still going to stick with my prediction though and say it will.
