'BC and old retro games are stupid'. Shortly thereafter the PS1 classic is announced.
'We have no plans for a future handheld after Vita'... I wouldn't take that too seriously, no reason(s) in particular.
In Sony's defense. Nintendo has proven that these plug and play retro systems make a lot of money and Sony would be fools to leave that kind of money on the table, especially with how much nostalgia is behind the PS1. While the Vita at best barely made them any money.
