Looks like a cosmetic change only. If they made it rwd with the 3.3 V6 then you have a 350Z and RX8 competitor with the right suspension tuning.
That or turbocharge/supercharge the 2.7L V6. I've already seen quite a few blown V6 Tiburons here. They also need to beef up the clutch/transmission. A Tibbie with a prematurely worn out clutch is also a pretty common sight.
