Well, between both the Spring and Summer OVAs, we've got enough fanservice to last at the very least a 26 episode series. Guess that means Shaft is going to stick to its not-so-much-fanservice-if-any-at-all style for the TV series, lol.
Of course, they could be just waiting to drop a nuke bombshell on us in the last episode and flood our brains with rampant fanservice in the finale.
Personally, I'd like to see that. Just to see if and in what way the anime community blows up over it.
