they replaced the entire animation team after episode 10...
the funny thing is shortly after episode 10 past the library arc the anime went on a downhill spiral that couldnt be stopped
i think it iwll be a completely new animation that shares story similarities with the first season. maybe things like how negi and asuka meet are the same and such but what happens after might be changed. alot of the filler will be gone hopefully. maybe more expansion on evangeline and chachamaru. and the biggest hopeful wish is that the pactios are put to partical use and impact the show and asuka is the tough cookie she is supposed to be.
one of the biggest disappointments in the anime is how it wasn't as ecchi and didn't have as much fan service as in the manga
yeah.... actually that wasnt on my complaint list.... lol....
