dacaw - Ultimately it may have to do with bandwidth (2 slots vs. 1), but I don't know that they've even begun to approach saturating PCI-Express x16(though IIRC they don't actually both run in x16 mode). Also, for those who've laid down some serious dough for a high-end card, it offers a way to stretch out that "investment", by continuing to use it with another, perhaps less high-end, but later generation card(if they get things to work with non- identical cards, like I've read that ATi is already doing and demoing.
Putting 2 GPUs on one card is bound to get crowded and require more layers in the circuit board, as well as presenting cooling challenges.
