There is a lot of talk, but no action, I'm afraid.  NASA has produced pretty
design sketches for a "Shuttle II", showing various approaches, but nobody
is funding development or likely to fund it any time soon.  (It *is* time
work got started on this, but...)  Even these designs typically don't
qualify if you take "similar capability" literally, since they are mostly
somewhat smaller than the existing shuttle -- it's over-sized for the bulk
of the users, having been driven by a now-irrelevant USAF requirement.

(For purposes of this discussion I ignore seriously different vehicles,
like SSX and the various small spaceplanes, which are getting active
attention in various places.)
