If you can wait, I would hold down for episode 11.5 from Hyouka. They released it on the web but I have hopes that they will had it to the blu-rays! The scenes are totally worth it, it's a summer special in a amusement park!
Besides Haruhi, you also have Card Captor Sakura (Episode 63), Toradora (Episodes 7-8), Hanasaku Iroha (Episodes 16-17), Ouran High School Host Club (Episode 7), Code Geass (sorry but don't know for sure the episodes of this one)
This are the ones I could think of ^^'
