To continue beating a dead horse: Haruhi Szumiya baby!
Tsubasa Chronicle - The end of the second season was pretty bland and felt rushed. Kind of like Mashimo stuck it on the back burner. Well considering he was doing Roots and El Cazador yeah very seemingly why. Tokyo was a really good OAV but I've been hearing mixed reaction about the new one.
Fruits Basket - So much more I loved this series and it just could have had more
1. Air Gear (Cop out ending is a cop out ending)
4. Nabari no Ou (If it does happen a manga adaption that doesn't give off a yaoi vibe ending would be much better)
5. Darker than Black
Gakuen Alice (PLEASE)
Lucky star (although I think a short OVA would be best like maybe a 6 episode OVA)
lyrical nanoha (another strikers or one that takes place between A's and strikers. ANYTHING IS GOOD)
(Though not so soon->manga reader's should know why(gimme the latest manga chapters NOW)->also avoid fillers which many people complain although I love/like it)
2. Rave master/Groove adventure Rave->seriously, need a complete ending for this one and there are fricking lots of materials to use too. Hope some studio would pick it up.
3. Ghost Hunt
4. Tsubasa Chronicle OVA/OAVs->
need more when there are also many materials too as well as the manga almost end
