|Will previously defined variables be availiable in the block?

Yes.

|Will variables created in the block be availiable outside?

This is not directly related with <>.  I haven't reached conclusion
for this matter.  I've explained this before (sorry, message number is
not available now. I wish I had faster connection).

|Is it planned in 1.7 or later?

I don't think it would be available in 1.7.  I want to introduce it
along with nested scope enhancement.
