There is no lvl 65 gear, even the chinese servers have no lvl 65 pvp gear and they are on patch 1.62 last I saw.
We just did Patch 1.45 over 3 months(November, December, January). This introduced 55 PvP Gear, 60-68 Content, Wings, Mounts, Spirit Covenant, etc etc.
Patch 1.5 has Fashion, 70-78 Content, Battleground Changes, Tower of Trials, Market change, Astral Optimization, Chat Emoticons and some other stuff not going to bother listing it all you'll see it when it's out. It's a big patch will be separated into probably 2-3 patches one a month. Will the first one be in February? We'll see.
The game will follow the same pattern that the original game released them at. While yes the suggestion thread does matter since it also sends more ideas to the devs for future content / little changes here and there.
They won't do updates over night do multiple ones a week, they will be spaced out and done over time.
