The development of blocks for 2.2 has started, but as others have already pointed out, it might take time to get it implemented and running well.
So, I would suggest that we change our development plan a little bit and consider adding those features to our 2.1.x code base that are independent from blocks, like e.g. the virtual sitemap components etc. Of course we should take care that the changes are not incompatible (apart from the one below :) ).
+1. Please consider also sitemap logging as discussed in previous threads (<map:log>): I really feel a need for that, especially now, given the sometimes hard to debug roundtrips between sitemap and flow...
