So far, in terms of sales, i see that both x360 and PS3 changed their places compared to last year.

In 2008 main x360 model, x360 pro reached 299$ price point, while PS3 just moved from 40GB to 80GB.
This year, main PS3 model reached 299$ price, while x360 model moved from 60GB to 120GB.
Sales so far are pretty much same, but i think PS3 will perform better than x360 last year(it already does, because of Slim model). Maybe x360 also will do a little bit better than PS3 last year too, but i`m not sure.
However, 199$ costing Wii could be a problem for both HD consoles in West during Christmas. In Japan, price for Wii was never a problem.
