The Official Site has been updated for the second season and you can watch the preview for the first episode here (looks quite good).

Staff for episode 1 – Dangerous Race:

Script: Hiroyuki Kawasaki (He wrote all the episodes for season 1).
Storyboard & Episode Director: Hiroshi Morioka (worked under the same charges for episodes 1 and 12, not to mention he is now the series’s director along with Koichi Mashimo).
Animation Director: Minako Shiba (character designer).

The staff is pretty much the very same for the 1st episode, which was one of the bests animated episodes, so we can expect good stuff for this one.
