According to www.lucasarts.com
Battle For Naboo is being ported to the PC very soon.
Just looking at the screenshots, it appears the resolution in this version is much higher than the N64 version (as one would expect). Not sure what else is really new though (if anything).
Of course to those of us expecting the upcoming PC announcement was going to be a new game, well I'm sure we're a bit disapointed. ; p
