10GigE fiber will be the better choice in the long run....

Until the distances become reasonable, it will probably be a connection of
opportunity. Instead of nxGE you can use 1x10GE for an MMR x-connect. The
question is will people be converting 10GE copper to fiber to bridge the
distances and then back?
There are no highly dense 10GE platforms that I can think of right now, much
less cost effective ones.
