Is Sony about to reveal a PSP3 at E3 2017?

Users of NeoGAF have been talking about a possible successor for Sony's Playstation Vita lately as, according to Chinese games media who got an invite to the event, Sony is going to present 'new hardware' at this year's E3 conference to fight Nintendo and the Switch.

Further evidence is given by Square Enix's CEO Yosuke Matsuda, who recently mentioned a "PSP3" in an article, too. None of this is a solid confirmation, so take it with a pinch of salt, but the rumours are interesting nonetheless.

Is it time for the PSP to make a comeback?
