Who cares about the exact difference at this moment? The fact is that it isn't a bomb and Sony's not going to dominate alone with no real competition to keep them giving and honest. No runaway console monopoly in sight, basically. So, I feel that this is very good news, all things considered.
Exactly. It was the competition during the PS360 gen that drove Sony to become a better player (or at least give off a better image that has resonated better with gamers) this gen, while the lead-up to this gen forced Microsoft to reinvent their approach. All in all, it's good for gamers.
