Just to add my two cents, I'm going to say that there's probably better things to do in our lives than tallying up sales charts for consoles and video games when none of this really applies to our everyday lives, unless you're stock holder, in which case you're on the wrong forum.
The Christmas season is a good moment for Sony to push the Vita, that's what this thread is all about. Some interesting bundles are coming up and it's entirely possible that they'll boost the sales significantly, and if proper marketing is added into the mix, those sales may stay up. We've already seen how certain releases are entirely capable of turning the situation upside-down - Project Diva alone casued Vita sales to increase by 500% in Japan for a brief period of time - the more games it receives the more interest it will get from developers.
Clearly the console is a slow starter, but as the adoption rate reaches a given level, the games will start flowing like a river - it's simple as that. Sony already stated that the Vita is expected to have a life span of aprox. 10 years and knowning Sony, they'll stick to that even if they have to keep in on life support for the first few years.
