That's simply not true. Every newer card from NVidia (that is, every
G200-based card, right now, GTX260, GTX260-216 and GTX280) supports DP,
and nothing indicates that NV will remove support in future cards, quite
the contrary.

The distinction between Tesla and GeForce cards is that the former have
no display output, they usually have more ram, and (but I'm not sure
about this one) they are clocked a little lower.
