Yes, this "shortage" in Japan is only temporary, plenty more games will ship by the weekend.
Think of it more like a few days delay, maybe that'll help.
Anyway, I doubt this will happen in the US, I'm sure they'll be able to produce enough.

Bet with disolitude: Left4Dead will have a higher Metacritic rating than Project Origin, 3 months after the second game's release. (hasn't been 3 months but it looks like I won :-p )
