New Brevoort Formspring

I was super stoked for Uncanny Avengers, but then I thought the first few issues were just so-so. Now, I think Rick has really hit his stride and I'm totally loving the book. I love that a lot of it ties back to his work on X-Force(which was the best book you guys were putting out the last few years and I'm not even that big of an X-fan). Also, I was never a huge Acuna fan, but his UA have been awesome. Any idea how many more issues he has planned? I assume he will need a break at some point?
