Zotac is developing a GTX260 with DisplayPort outputs, in place of the usual dual-DVI or dual-HDMI ports.  expreview has their hands on an engineering sample.

Zotac GTX 260 with DisplayPort engineering sample temporarily replaces one port with DisplayPort, so you’ll find DVI+DP+TV-OUT at the same time. The DVI connector can support D-Sub or HDMI output, which provides better flexibility when users need to build dual-screen output.
