Well, the plan is for 6.6 to have impredicative types, and revised
GADTs. I'd like to fix the interaction of type classes and GADTs too.
And we'd like to have shaken down the parallel implementation a bit.  

The natural time for 6.6 feels like at least 3 months from now -- and
we'd rather not get pinned down to any dates for a while yet.  If the
reason you want 6.6 is to get a new Cabal, why not download a new Cabal
package?  Or is there another reason you want 6.6?

Bug-fixes to 6.4 are a much smaller deal.
