While it seems ridiculously unlikely at first, it's actually quite possible.
Let's say that all the 10 Vita games shown at E3 launch in 2013, for simplicity's sake. If 2013 managed to match the PsP's best year for game releases - in terms of sales - that would mean 23.37 million for the top 10 best selling games . That's for 2006, and I don't think any of the other years match that.
Considering that the Vita is looking to be far less successful than the PsP, managing that is quite unlikely. It's also unlikely that all the games will be shown off at E3. But even if the Vita somehow managed to manage the PsP's best, 23.4 million is by no means impossible to reach for NSMB2.
This is a really nice prediction thread, because it hinges on several things. One of the best I've seen on here in a while. Personally, I'd give it somewhere around an 80% chance of happening.
