How many more/less millions will the PS3 sell in 2008 world wide

[Bodhesatva]

I think a 15-25 percent increase is doable for the PS3, for a variety of reasons.

That would put  the PS3 in the 9-10 million range. Or, put in words: solid improvement for what has thus far been a third place console (most third place consoles decrease in sales), but nothing earth-shattering where suddenly, everyone in the world gets it and the system doubles its sales.
