a77 for events/weddings - now or wait?

I just bought an a77 and used it at my first wedding.  It is a solid camera.  I haven't learned everything about it yet, but, I had a good time using it.  I also use it to shoot sports.  I can't wait to shoot football and water polo with the 12fps!

However, if you are making money with you current rig and your clients like your work, it is more profitable to wait!  Waiting is not as much fun, but it is economical. I had an a700 that failed on me one week before the wedding.  I had no choice.
