regarding Design:
- alternative background themes would be great
- alternative background music (like in pulse)
- possibility of playlistmixing like in pulse (custom and original tracks)
- the 321 countdown is quite boring / doesnt fit somehow imo (imo!)
- start / finishline is not visible enough in some tracks (like in Vineta K)

regarding Extras:
- i miss those stats, too
- i like the "profileview @onlinerankings" suggestion mentioned here before. For comparison purpose etc.
- replay mode with telemetry data would be great
- skin creator (despite the complexitiy it is asked for
- ship editor (may be more complex than creating skins, but it would be great)

regarding Modes:
- Eliminator
- more options for online mode

Someone mentioned a 2 player splitcreen online mode. But if u think about it, you may come to conclusion that this wouldnt function properly- cause of the following reasons imo:
- at the moment there can only be one player signed in at the PSN per console (so how to register the second player?)
- 2 players online per console would mean to synchronise 2 players with the only connection u have. That would mean to manage code for 2 players with singleconnection
