The way I see it, Sony did not come back. From reports, the PS3 cost Sony all the profits from the PS1 and 2 so I higly doubt that Sony will see this as a come back. Sonly lost the US. MS has taken the US and at least one major terrority in the UK. WIth the US being one of the biggest game buying market, thats a huge lost.
The only thing Sony has gained is maybe the worldwide total but its a hollow victory if your console bleed you money for so long that as far as profits wise, its lost you a lot of ground and put your company in the red.
As far as I know, Sony sells in more markets than MS especially in Europe so its easy to see them sell more there. Of course MS has no market in Japan which is a huge different in the global total sell.
Maybe history will have the PS3 comback but then again if the person writing the history is balance, it probably would show the cost of winning can be steep.
