I'm not sure if PS3 will get ahead of Xbox360, well see int he couple of weeks, because X360 will more likely get a bigger boost in HW than PS3, especially in Europe, for the sole reason of being able to run a pirated copy of GTAIV. Plus, no killzone 2 and new FF before 2009.
It's very hard to tell, but i simply think that MS still has more manevaouring space regarding pricecuts than Sony, R&D costs for PS3 were massive, and it still hasn't taken off, while MS took cheaper aproach in R&D, and would probbly loose less money with yet another price cut. If they fully sort the reliability problem out, i think they're going to be on a winning streak.
But i don't know jack :)
