The launch allotment is looking to be more like 150k - 200k instead of the 400k which is down from the original world wide 2,000,000, but there may be as many as 750k systems shipped by the end of the year (yeah right). IGN Link: http://ps3.ign.com/articles/746/746181p
Further more, it has even more problems (then we thought). Here's another IGN link: http://ps3.ign.com/articles/746/746492p
Retail store units are over heating. The system can't scale images (the 360 upscales your old games and can upscale 720p games to 1080i). Etc, etc, etc.
Finally, Merrill Lynch seems to think 360 is going to be the dominant next-gen system through 2011. This seems possible with MS estimating a total of 10 million 360s sold by year end vs. Sony's lack of systems. Final IGN Link: http://ps3.ign.com/articles/746/746196p
As much as I want a high def video player, I hope Sony bites it on this one.
