I don't, I'm making an educated guess. The G71 and G72 cores are similar but more effecient than the current G70 (7800 series). It's not that hard to imagine a G71 core on existing cards. Of course, if the power requirements go up a mobo revision will be required since mobile vid cards get their power from the mobo instead of directly from the power supply.
As far as SLI or dual GPU cores on a single card, those are both very, very power hungry graphic solutions for a mobility platform. Without a radical improvement in battery technology I have a hard time imagining either in a laptop with a battery life more than 10 minutes or so.
But that's with current technology. Two things could make them possible in the future. The first would be a very clever power management scheme in which one of the GPUs was turned off under battery power. The second would be when nVidia goes to 65nm or 40 nm dies. The drastic reduction of power requirements for 65nm or 40nm chips might facilitate a dual GPU solution in a laptop.
That said, I did find one site that claims dual SLI 7800s will be in a 900T chassis by February.Nvidia GeForce Go 7800GTX SLi Notebook Coming Soon...
