I'm still unsure if I'm going to get this or not with as much as I'm still enjoying Driveclub. Plus Forza 6 was just announced for later this year and I'm sure Gran Turismo 7 will be coming in 2016. Project Cars may be the one that ends up getting axed from my purchase list, unless of course it comes out and completely blows the doors off of everyone's expectations.
Truthfully I'm so spoiled by Driveclub's visuals, the actual in-game videos I've seen of PC look nice but it almost looks a little "flat" and...I don't know, clinical maybe compared to how awesome Driveclub looks.
