I took 3.5M and 5.3M, because that is how much PS3/360 sold last year. And this year, they`ve changed their places. I mean, PS3 got pricecut and x360 got additional 60GB. But why x360 sales would go up(over PS3`s last year sales) without pricecut and on 4th year, is beyond me.
I don`t expect PS3 to sell less than 5.25M for the rest of year and don`t expect x360 to sell more, than 3.5M either. And 1M was upper/lowest limit for both consoles. Possible or not, we will see after 12 weeks.
Yes, x360 has strong positions in NA, but so and PS3 now with 299$ price this year, which i expect will result in PS3 taking x360 NA sales.
