A much cheaper PS3 would definitely move a lot more boxes this holiday. From what I'm reading in this thread, I'm guessing the chain of logic is as follows:
If Sony releases a slim PS3 in time for Holiday Sales,
and if the slim PS3 is cheaper to produce,
and if the big-gun games announced can move boxes,
then the PS3 might outsell the 360 and the Wii.
A lot of ifs in there, but if they execute flawlessly they might have a great Christmas. Will they "win" Christmas this year? Probably in Japan. Probably not worldwide, unless the competition sits still. I know some posters keep assuming that unannounced games mean they won't be released, but that's not a safe assumption.
One of biggest ifs for Sony has always been execution this generation. They need to meet their own objectives once in a while if they want to pull this sort of thing off.
