Seeing that the Crusader in D3 is going to have an ability to mount in combat - expect some form of a spectral Charger as an ability in 6.0. I would still like to see each spec have an aura that works well with each spec - Holy given one for interrupt/silence immunity, Prot with damage reduction, and Ret with damage reflection. I still think that Seal of Justice will get the Holy TV treatment as a way to combine the PTR they had not too long ago with the current T15 4P.
Oh, and most importantly: Give us a new Avenging Wrath animation. The paper wings were nice in 2007, but they desperately need an update.
