Its likely, since Nvidia have advertised surround coming with Fermi. 3D vision support for now and 3D vision surround support when they release Fermi. :)
PS and I discussed in the other thread that Nvidia might bring mosaic SLI over from Quadro and thats a software solution that Nvidia could have introduced years ago to enable 3 screen support on even 8800 cards.
Edit:
Just found this link confirming that you need SLI for 3d vision surround:

Edit 3:
According to Techreport, Nvidia will add bezel management to 3d surround:
Nvidia says it plans to add a bezel correction feature to its drivers, which apparently wasn't working in the demos we saw at CES. That should help further the illusion.
