Ps3

[Lirange]

Thinking about buying the ps3 in a couple weeks but should I wait? I read an ign article about a possible price cut in august.how significant are price cuts usually? And if I do decide to get a ps3 what model should I get? if I only plan on playing games on it the fat 40/60 gb will suffice right? The memory will just be used on saved game files right?and if I do need more memory I can just get an external hard drive can't I? And if I get the ps3 is there any thing else I should buy for it? I'm guessing an hdmi connector to play in hd but anything else?
