Sony is really rocking in Europe.

It will be interesting to see how the United States turns out this year. I expect sony to gain an early lead once they finally sort out their supply issues, but I think the xbone has a much stronger announced 2014 lineup for the American audience. It's just the question of whether people thinking the extra $100 is worth that lineup.

Europe sales are depressingly one sided though. Makes the charts and sales information boring imo. Xbox desperately needs a competitive price there and sony would need to do something mindblowingly stupid for the other consoles to even come close in sales.

Sony have a firce fight for third parties.... with nintendo... on a console, un no.

Yes Japan is a trend oriented nation, in case you have not noticed PS4 is a world wide trend.  Japan is gonna eat it up.

Can someone make a comparaison between ps2 and ps4 i had the feeling that ps4 will sell nearly as ps2

New week, updated charts. Now I'll wait for the japanese release to update these charts. They already show us the "slowdown" of each console. Wii U's is quite severe, whereas PS4 and Xone promise to keep an interesting (but not amazing) rate. PS4's supply issues seem to be gone. USA appears to keep the close battle between PS4 and Xone. The former has sold a little bit more in total even for the same number of weeks, but the latter is selling more in each of the last 3 weeks.

Way too early to tell what happens anywhere really. PS4 is still sold out everywhere so at least wait until all consoles are in stock to see what demand right now is.

Unfortunately, VGC doesn't have weekly data for PS2 (as far as I know), so I cannot make that comparison.

I believe PS4 can do similar or even better than PS2 in the short-term. In the long-term it's unlikely, since it has significant competition (coming from Xone) while PS2 was a sole queen. Furthermore, the whole market is shrinking, so every one's slice will be smaller.
