120-160gb ps3

so i was about to go to the store and buy a ps3 (80gb) when i came across this article

anyway i was wondering if the 120 or 160 gb ps3 will be worth the waiting for, seeing as it will be the same price or do are you guys having trouble filling up your 80gb as is.

also if anyone knows the release date of the higher gb systems please let us know.
