Aha. It appears I was correct in framing my knowledge as out-of-date. 
It looks like the technology has advanced, and that 10GE on MMF or SMF, single-channel, is what the current state of the art is, and at the $2k-3k unit price.
In which case, yes, not offering this (and not building cards to use cheaper and/or more flexible component, ie XENPAK), is likely going to be a huge mistake Cisco. Unless they bite the bullet and do whatever it takes to make xenpak-based 10G cards, on at least some flavour of card on any 10G platform.
(I don’t really expect a xenpak-compatible version of soho routers to show up, although it would be nice as an option on most of their switch families.)
So, I sit corrected. 
BTW, thanks for pointing this out; it’s nice to see that things haven’t completely stagnated in the last couple of years.

P.S. At that price level, I actually do expect another Swede will have, or already has, one or more of this class of box at home. In his WC, even.
P.P.S. He’s not crazy. But he should have a t-shirt that says “I’m with STUPI”.
