Sounds about right.

However on doing a quick web search that in fact
is the estimated current background temperature.

According to

http://www.advancedphysics.org/forum/showthread.php?t=8749

the posters there think the final temperature would be below 1 K.

And according to Wikipedia, any guess is dependent on whether one
uses a closed or ever expanding model of the universe.

Ah. A bit like how much money will we end up with at the end of the
world. 2.7p or 1p, depending on whether infinite economic expansion is
possible (the Ponzi cosmology) or the latter, the Malthus cosmology..
