A reliable source close to the Development Studio "Turn 10" contacted Addict Gaming earlier today with some pretty substantial evidence that Turn 10 will be developing Project Gotham 5. We can't post the e-mails and invitations we saw earlier today due to keeping our informants identity hidden. What we saw though is definitive evidence that not only are they developing the latest addition to the Project Gotham series, but they'll also be announcing it "Within the next two week's, depending on next weeks NXE announcement". Looks like we'll be in for a two for one!

I don't see it myself, I think T10 will be currently busying themselves on FM3.

Good, I have really enjoyed playing PGR 4, so the fact that there is a sequel is good news

Yeah the best Arcade Racer of this gen will have another sequel. NICE !!!
But I hope Turn 10 will keep the arcade-ish style of the game.

I thought Grid was vastly superior to PGR4...but it is still a great racer.

I don't like real racing tracks and GRID had too many of them and also too less exotic european cars. (Ferrari, Lamborghini)

pgr3>pgr4

but both are underated and should have deserved much more sales attention, instead people run out to buy crap like prostreet

If this is true, then they probably won't be working on Forza 3 for awhile.
