Looks like Polypony are full steam ahead with Gran Turismo 6, then, with Bathurst on the cards.
A YouTube video (of a conversion) is doing the rounds – here – with the video taker getting the info from the developers.
“I study at the Mt. Panorama Motorsport Training centre Bathurst and can tell you that a large team from Polyphony are currently at the track mapping it out and getting all measurements for a new game,” he says.
“They have been there since Monday and we were wondering what they were doing, but found out yesterday who they were and what they were doing because track management told us as their helicopter was going to be landing next to us during the day.”
“I’m assuming they will be there for a few more days.”
Presumably this new game will be for PS4 – or, hopefully, PS Vita.
