At this time, IJSK will not be released on the PS3 and Xbox 360. That's okay -- those consoles have a number of games that aren't on the Wii. What separates the Wii version from the PSP and DS editions (aside from the latter two being hand-held platforms) is that the Wii has an exclusive on it: Indiana Jones and the Fate of Atlantis will be added as a fully playable game.
So that means anyone who has a Wii will essentially gain two games in one. That's not an understatement, either. IJFA is extremely difficult to find now (it was released in 1992) and most copies for sale on eBay can be quite expensive. In addition, it's assumed that IJFA will be the "talkie" version, so full voices are expected.
If you have a Wii, this is definitely a game to pick up (espeically if you haven't played Indiana Jones and the Fate of Atlantis).
