So we have Hedge Magic out in a few weeks and RoP: Faerie, then the Rogues' Gallery of Open Call, then....?
Tribunals? 
Perhaps the Theban Tribunal? (ohYES!) Or a look at Hibernia?
Something on the Mythic Church? (please!)
A revised Ordo Nobilis?
Just curious!
-Ben.
I agree, would be nice to hear what's coming next year. I'm all for a new Ordo Nobilis, with an expanded or reworked combat system, rules for nobility and how to use it in a campaign without trampling too much on the historical politics of the time. 
As for Tribunals, I suggest a new look at the British Isles. Wouldn't it be possible to actually throw these three tribunals into one book with one theme?
But I'm really looking forward to RoP: Faerie, and the Ars Magica take on the Sidhe, for example.

Hum... Just looking forward for new ArsM books 
The Fixer, Ars Junkie 
There are two titles that I actually have finished manuscripts from David for, after ROP Faerie:
Tales of Mythic Europe
Magi of Hermes
They've not been formally announced yet, so I can't give any more info, but I thought you might appreciate this little hint, anyway.
Fantastic, thank you!
-Ben.
Yay! This looks good.

It's going to be called "ToME"? That's just perfect. 8)
