It's not just us in North America, it's Europe and Oceania that also have to wait to find out. The only VC games us non-Japanese get to know ahead of time are TurboGrafx-16 games, and that's only because of Hudson Soft.
As for Gradius, does this mean Midway will want to add both the SNES and Genesis versions of Mortal Kombat (blood/non-blood) and Mortal Kombat II (SNES had blood, and better graphics)? I wonder if Nintendo will release the SNES version of Wario's Woods?
