In January Nvidia announced it was working on an ARM processor called "Project Denver".

BSN has some information on it's progress now.

It will be an 8 core ARM processor, either a Cortex A15 or something called PD (can't find any info on what that is). Will include a Fermi based 600 series GPU with 256 CUDA cores and PhysX support. The 8 core ARM processor will include 64 bit support and probably be clocked around 2 to 2.5GHz.
This thing is gonna be too big for phones or even tablets, seems it's primary purpose is for servers, but Nvidia is working on a chipset for desktops and laptops too. The motherboards will include USB 3.0. SATA 3.0, and PCI-E 3.0 support.
I would imagine we may be seeing some laptops and low end desktops with this running Windows 8 ARM edition.
