The only things PS3 owners have to look forward to is the new Ratchet and Clank game and MGS4. Other than that, it's nothing. Killzone 3 will suck like the first one. (BTW, Killzone:Liberation (PSP) was actually Killzone 2.)
Xbox 360 is still cheaper than the PS3. Besides, there's really no reason to think up of a hypothetical situation where the PS3 and Xbox 360 is released on the same day. PS3 lost by being released. As for that price drop, they really just used turd polish on crap-ola. Kinda like what they're doing with Killzone 3.
It's useless. Name three people who have a PS3, but not a PC. The PS3 is not a gaming machine. It's still an overpriced piece of technology. Blu-ray and web browsers have nothing to do with games. Gameplay does, and the PS3 brings nothing to the table.
