I think there is no way we can even make wild predictions before this holiday season. Thats why I said my "prediction" is a guess. PS3 could still win. If the rest of Sony's big titles for PS3 this year get good reviews and sell well, and PS3 gets another $100 price cut in USA and a $200 price cut in europe, and then FF13/MGS4 ect Do end up coming out next year, and are really good, and sell well, PS3 could come back, beat 360 by next summer, close in on the Wii by xmas 08, and then overtake the Wii in 09. Its a huge longshot, sure, but until we see that PS3 infact does sell poorly this christmas, there is no way to really know.
Also, there is no way the PS3 will have under 10% market share. If it did, sony may as well drop out of the console market O.O Itl'll have 15% at the bare minimum
I personally think the Wii is going to win, seeing as its the most likely. But there is no reason to flame people who think the PS3 will have the greatest market share- its still possible.
