Looks like WordPress 3.3 is getting closer to a stable release. Lots of bugs have been addressed in this release. It's worth testing 3.3 out if you have time but I don't advise you using it on a live site just yet Announcement post can be found in this article: WordPress 3.3 Beta 3 Available
To be honest, I'm not really a fan of the new dashboard side menu, but I really can't wait to see for myself what 3.3 has to offer. I just hope that my theme will be compatible with it.
Yeah your theme should still be ok. I don't think WordPress could change anything that would make older themes break. They tend to keep backwards compatibility for quite some time.
Had tested 3.3 beta 2, I wont be trying this time, November 15 is approaching, and will directly use 3.3 stable. Hope 3.3 would release on November 15.
I never really test beta Wordpress. So kudos to those who do test it so that people like me can use stable version.
