I just finished watching Lucky Star Episode 24 and I guess thats its for the series. I’m sure all the fanboys and fangirls just can’t get enough of the show.
But I must say that KyoAni is a great production company. I’m sure they purposely arrange to show the entire Motteke! Sailor Fuku Dance for one purpose. So that every fan out there can learn it.
I’m sure everyone has seen the various Hare Hare Yukai Dances out there. Where masses of people just run onto the roads of Akiba and start dancing it.
Now that we have seen the full version of the Motteke! Sailor Fuku Dance. Its time to practice hard and then move onto the streets!
I’m have a good bet that there would be a second season since it was such a popular series. Well till then we can satisfy our craving for Hinano-san with the upcoming Haruhi Season II.
Even though I never watched Working!! myself (wished I did), I... – 
There are few characters that haven’t been seen yet (compared to the manga). There is another teacher we see with Akira & Minoru, and another student in 2nd year for instance…. so, I hope we’ll see them in a next season
