Hi Snorks
Welcome back
We're currently working on two developments, both close to launch now.
1) ROF2 support (beta is imminent)
2) all new t9 content (have a look at the server updates forum for more information)
There's nothing "after VT" but the new t9 content will be perfect for players who have done VT; some of the gear is the same level if not better. Just bear in mind there are some prerequisites not in t9 (it's a new story line starting in t7, speak to Ghillie in THV to get started and Azakir the storyteller in THF for the lore).
T10 is planned and is on the drawing board. Perhaps not this year though. Before that, we're going to do some work on other areas (epic 3.0s, both new and enhancing the existing quests to make them less grindy and some more work on a group pathway for players that can't necessarily raid a lot or at all).
And lots more planned besides.
