Smash WiiU took a long time before it made any impact on the charts. Stayed a long time with 20-40 points till a few months of it's releases.
Going to compare the 2? Why not with smash 3ds at the very least
Because I looked it up a few days ago. I just point it out because it isn't like Pokemon who gets massive pre orders from basically day one. Doesn't have to be the same this time but we shouldn't be surprised that 2 months before it's release it isn't higher than 300 points while ending with +1000 points.
