It will be lucky to make it to 15 million, as of this moment. All ninty fans bought the console when Mario Kart came out and so that is why SSB didn't boost sales so much. It's a dead console and news on an upcoming ninty next gen console are just helping it drown faster.W

what upcoming console? did i miss something

There have been a bunch of rumors, here are some links:

Here is a quote from the article which shows that nintendo is working on a next generation system:

"Back in May Nintendo already confirmed that it had started development of its next-generation home console. In October it also transpired that the company would design system-on-chip for its forthcoming system in the U.S. According to a new media report, Nintendo contracted AMD to provide graphics processing technologies for the device."

Just like how Microsoft and Sony are building their next platforms.
