I'm not sure how much I can give away. It's been an interesting few months.
A lot of the team who've been on the project for a long while (myself included) have not had as much spare time as we used to for Riven-related things. However we've expanded the team several times since Christmas - and the new guys are working hard!
I can't tell you what we're working on, but I will say we're doing something a little different. I expect that soon we'll introduce you to the new team members and at the same time break down what we've been up to since the last update.
