GT5 is considerably bigger and will most likely have a much better physics engine.
Plus, GT5 has NASCAR (meh) and WRC (hurah).
Bets are GT5 will beat Forza 3. However, will the games actually be reviewed side by side? Probably not, so a metacritic comparison probably won't show much. After all, if they did, how do Wii 'games' gets above 40...
