Hmmm, just been watching some vids for F1 2011 on 3DS and Vita. I was always led to believe the Vita ver was a straight port of the 3DS game so never really paid it much attention. But having watched a few videos, they look to have improved on the visuals in quite a few ways, including better vehicle models, textures,lighting, they also have real time reflections on the Vita version.
This may very well turn out to be a pleasant surprise. It didn't review badly on launch for Vita either (average score of about 7/10). And lets face it, this is probably going to be the only portable Codemasters title we see on either system now.
If anyone's interested in the comparison - 3DS ver:
