No chance as even some pretty staunch PS supporters have already noted. X1 will be over 4 in a week or three when PS4 is around 6.5m I think. So 3.5/1 sales ratio needed to hit 10m b4 5m. Enthusiasm's great but you're setting your bar too high.
Someone mentioned big system movers I believe MGS4 is still the champ with around 220m pretty directly attributable PS3 sales in the weeks around launch. It would be wildly optimistic to expect X1 sales to jump that much. T-Fall is a new IP compared to MG, the preceding PS fanbase was maybe 125m at that point and extremely loyal. Lots of other factors, genres with shootism as a possible plus for TF, similar release dates and length of time after console release(?). I should look this stuff up but I've really gotta run. It's possible 200k extra boxes could move in the weeks around T-Falls release but where's the baseline to judge from? Just sayin don't get too high and you won't get too low. Later.
