at 10G the optics costs are about 1/3 that of SMF (SR vs LR).

We tend to keep things SMF, but within many older datacenters MMF is broadly available and does meet the needs at a lower cost.

There seems to be a shifting trend as well in UPC vs APC connectors.

I think much of this problem is clearly articulated here: http://xkcd.com/927/

Everyones needs are a bit different.
