I would be very wary of going HTML5 now. We just did a major upgrade to HMTL5 and EVERY IE7 browser couldn't handle it. We spent three days and nights rewriting to satisfy the tons of IE7 users.
IE8 isn't much better with HTML5, but at least it works.
And forget about 6. I just told people flat out that we don't support 6 anymore.
So for my next site we will avoid HTML5 for about 6 years.
