SNK Playmore sent a press release out announcing the lineup for their SNK Arcade Classics Volume 1 collection for PS2 and PSP. There's no mention of a Wii version, but a Wii version is listed in the game's ESRB rating, and it was discussed at TGS. We hope it's not a mistake, because we love old games, and this lineup is totally hot.
We kind of suspect that this isn't actually coming to the Wii, because of the 16 games on the disc, 7 are already available as Virtual Console downloads. Metal Slug, of course, is also available on its own disc. We have no issue with redundancy, but we doubt SNK would give people the option of either paying $9 per game or (judging by recent disc releases) between $15 and $30 for a whole load of games.
In terms of stuff that isn't on the Wii, the disc includes things like Shock Troopers and Samurai Shodown. Check after the break for the full, awesome list. Just imagine how much this collection would have cost in new Neo Geo cartridge form.
