Do you remember how long the PS2 was out without any upgrades? The PS2 is still going rather strong and they still release brand new games for it. It's such a good system.
If I'm not wrong, kingdom hearts re:com was released in november 08, which I am pretty sure every KH fan was waiting for it, which pretty much shows that PS2 even if its so old and crappy compared to the PS3 won't go obsolete. Hopefully its the same with the iPhone because it hasn't been that long to go bad...apple still sells the old white glossy imacs (the ones before the alum.).
