It's not targeted as a full-feature box AFAIK. You've got the ASR9k and
ASR9xx series for this sort of thing.

I do recall some mention of NCS5k supporting Segment Routing though -
that seemed quite handy for future MPLS P requirements.

I've heard some rumours to the contrary - presumably it could still be
canned. Tomahawk is still quite new, and the 9001 still sells well, so
perhaps the market just isn't ready yet. I guarantee Cisco's sales of
any given product proceed along these lines:

 1. Product sales for flagship $model are good
 2. Announce flagship $model+1 to public
 3. Product sales for $model plummet, whilst everyone waits for $model+1

Sometimes that's good, sometimes that's really bad. :)

I don't recall looking closely, but I very much doubt it due to the
reasons mentioned above.
