It's not really important, but the FAQ shows this question:
Q: Will there be new game modes / characters / maps / weapons for Rewind?
We have enough on our plate for the existing assets! Perhaps we could come up with a 'Street Racer Cortez,' or we could allow the community to build their own characters via Custom Mods.
And later the same question again with a slightly longer answer:
Q: Will there be new game modes / characters / maps / weapons for Rewind?
We have enough on our plate for the existing assets! It even includes Team Thief which wasa game mode from Future Perfect's Arcade League. Perhaps we could come up with a 'Street Racer Cortez,' or we could allow the community to build their own characters via Custom Mods.
