My prediction of the PS vita being discontinued by Jan 2014 is starting to look very likely. If it isn't, it will still sell under 20m units in lifetime sales (my other prediction).
My prediction threads:
Wii U will sell under 40m units (made on 14th September 2012)
PS Vita will sell under 20m units (made on 30th September 2012)
Wii U will sell under 7m in 2013 - I was right
