Sorry Skeeve but you've got 3 incorrect statements in a row here.

This is not correct according to independent analyst market research.
I cannot point you at most recent versions of it but you can see historic
versions of it from e.g. Crehan research at <
http://www.broadcom.com/docs/features/CREHAN_ServerIO_whitepaper.pdf>.

In CY2014 there will almost be as many 10GBASE-T ports shipped as those
SFP+.

Switches with RJ45 100/1000/10G-T are not rare at all.

For many server vendors, 10GBASE-T is often the lowest capex cost way of
connecting at 10G.
It also provides a nice upgrade path if e.g. not all infrastructure is 10G,
some servers 1G still.
