At some point in that PS3's life it got wet, or do you have very sweaty hands?
Naw, rust like that is fairly typical in humid environments. I've seen many electronics like that in Japan for instance. I'd imagine someplace like Taiwan, Singapore, Malaysia, the Philipines, etc. would be potentially worse.
It's not so bad if it's in an air-conditioned room as the air conditioning will remove much of the humidity from the air. If it isn't in an air-conditioned room, however, that's about what I'd expect to see or worse (I've seen worse).
