Do you remember when PS3 was going to be Sony's last console?

Hirai just mentioned at CES that gaming is one of the three pillars of Sony. If they did this well with the PS3 despite arriving later than X360 and the huge price tag initially (it's still as expensive as a Wii U model) then how can they do any worse after learning the lessons of this generation (PS4 hardware is not going to be as hard to make games for and as expensive, blu ray drives are cheaper and so on)?
