Sure, there are SoCs with PCI64/66 buses (Intel/Marvell?), but I haven't seen any solution where they offer that as PCI slot, save a couple of development boards. Is that perhaps what you're referring to?For a card with a bus interface of that type, I'd hope that the card is typical PCI64 in that it will work properly in 3.3V PCI32 slots.
Or better yet, if it's universal, 5V as well.
That aside, yes, I would expect that some embedded systems will start to grow 64-bit PCI over the next few years, but it seems a bit further off before we see Intel or AMD pushing the power consumption of their high-end CPUs really far down. (Yeah, batteries in the newer dual core laptops are suffering, but "who cares" in their eyes? ;)
I expect them to switch to PCIe, as that has the added bonus of less wiring to cater for on your PCBs. The newer Intel IOPs have PCIe links besides a PCI-X bus as well, iirc.
