@Samus More than one title was showcased at Paris, and knowing that the game would soon be playable (if only under a testing form) could have secured/confirmed a few purchase decisions.
I don’t want to restart an unnecessary debate, but Sony always announced Spring 2016 for the Beta release. E3 is within that timeframe.
As for VR, and correct me if I’m wrong, it seems PD said they were working on the feature but never confirmed it as such(?). I'm still skeptical they can achieve GT Sport VR on the Base PS4 model, unless they shrink down the gameplay and or assets in a substantial way. Knowing that no exclusive can be brought to Neo, assuring that compatibility may be a cause for trouble.
