Are the PAL / NTSC-J versions going to be included?
As there are some bugs in the NTSC-U version including unfinished Penta Penguin, which were fixed for PAL and then the fixes also carried over to the NTSC-J version AFAIK.
Considering that probably nobody will miss the PAL versions slower framerate, it's probably NTSC-J that is the definitive edition of the game.
