I am pretty sure that we will see a new Wipeout announcement at E3 this year.
Shawn Layden wore a Crash Bandicoot T-Shirt at Playstation Experience => Crash Bandicoot gets announced at E3.
Shawn Layden wore a God of War T-Shirt at Playstation Experience => God of War gets announced at E3.
Guess what he was wearing at last years Playstation Experience? Yep a Wipeout T-Shirt.
