Current themes

First - hey, I'm new. Hi. Blah blah really great stuff here blah blah!

I'm just curious - I know MU 2.7 is on its way out and I've seen a few posts about plugins and 2.7 and how they're being worked on and so forth...

My question is will the existing themes (which look awesome, btw) also be updated to 2.7 if any problems arise? Not rushing anything - I'm waiting for 2.7 to do anything major anyway - I just want to know if I should plan on debugging stuff myself or not.

Thanks!
