metal slug anthology availability

Assuming that the release date is right now (3/26/07), is Metal Slug Anthology going to be hard to find or should it be well-stocked on video game specific store's shelves (i.e. gamestop/ebgames)?

I've been waiting for this game to come out on PS2 as well, and I live in Europe (UK).

I see the PSP version a lot in shops, but I haven't seen the PS2 version yet.
