The source which revealed all this sounds too fishy.
I don't know how does a third party small developer knows about sony's pricing plans that too almost 1.5 years in advance. He might be right on the specs, but games list and pricing is debatable
Also $250 for PSVR2 with all those incremental changes, wireless, 4-5 hours battery life on 2560x1440,120hz is also too good to be true.
they couldnt make a psvita last 5 hours with 960 × 544 qhd screen
