While the Wii U won’t be an instant flop like the Virtual Boy, sales projections released by Nintendo show it probably won’t match the runaway sales success of the original Wii, either. Nintendo sold 3.06 million Wii U units worldwide from its November launch through the end of 2012. That’s nearly as much as the 3.19 million units of the original Wii Nintendo sold back in the 2006 holiday season. But Nintendo doesn’t think it can keep that momentum up. Back in October, the company said it expected to sell 5.5 million Wii U units through the end of March. That number has now been cut down to 4 million, meaning Nintendo expects to sell fewer than a million systems worldwide in the first three months of 2013. It’s natural to expect some sales drop-off as a new system transitions away from a holiday launch.
