The PS3 wouldn't be the lowest selling console.
When I made the next gen transition in 2008 I would've bought a PS3 if it had been cheaper than the X360 as I previously owned a PS1 and PS2. Oh well...
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
