It has changed a little from last year so i will point out the main changes that I have seen so far.
- Arcade mode has been given the axe. You have 3 modes now Low, Med, High Sim.
- Still has the Superstock, Supersport and Superbike series
- Cant seem to back it in as well as SBKX
- Handling is a little more touchy. The change of direction happens alot faster.
- Throttle response seems to be more notchy and maybe more realistic (I used to flutter the throttle to get out of corners quickly without wheelspin. Cant do that now)
- Graphics seem to be a bit better
- Audio of the bikes are a lot more realistic. You can now hear the traction control kick in and quick shifter pop.
- Computer opponents are alot faster. You cant simply outbrake them as easy anymore.
- From first appearences they have tried to bring braking markers, conrner speed and laptimes back to a more realistic benchmark.
Oh did I mention it has the new 10r

EB games has it for $49 brand new atm
