Campy comparison: Veloce 10 vs. Athena 11

[brownhound]

After missing out on well-priced used, alloy Campy groupsets here and elsewhere, I am leaning towards picking up a new alloy groupset. Question for those who have opinion or experience:

Veloce 10 or Athena 11?

Athena 11 is priced about $300 more than Veloce 10. Other than small weight penalty, what are the problems or issues with going with Veloce, especially with regards to performance and compatibility going forwards assuming that Campy sticks with 11?
