ps3 in 'others' sales have been beating the 360 (dont even bring up japan) this has been helping the ps3 beat the 360 in sales overall. the ps3 also has a lot of innovated ideas coming out this year (3-D, motion controls). we also have a great line-up of games that are releasing or are close to releasing. i think sony has this year set. it only took sony to drop Ms 9-million unit lead down to 5 million in 4 months i think sony can take the lead this year.
and i think 3-D will be the biggest push/help to thrive ps3 sales. people are really underestimating the market for 3-D and only sony and the very few with a brain know this.
also even if sony doesnt take the North American lead from MS just taking the lead in general with the help of others and Japan will put the ps3 in second place in consoles.
