That would be pretty damn dumb. The only thing PS3 had going for a long time was 1) a few exclusive titles and 2) free online. In fact, probably the only reason justifying having a PS3 when it was so much more expensive than it is now was the fact the online play was free. They know it, too. PS3 probably would have been a massive flop if you had to pay for online as well. Now it has some competitive pricing where they can probably experiment with stuff like that, but it's way too late down the road and they'd just piss off the fanbase that kept them in the console race.
