I read that GPUs are adding virtualisation features, are Qubes likely to take advantage of that?

If you mean second GPU passthrough then yes:

No, that is not what is meant by GPU virtualization. GPU virtualization is the GPU equivalent of Intel's VT and AMD's AMD-V, it's virtualization supported by the hardware which allows the GPU to be used by multiple VMs as though they were exclusive.

For some reason the GPU manufacturers have seen fit to limit this to expensive professional grade GPUs, but hopefully we'll see it in consumer hardware soon. Well, except I think Intel already has it in consumer chips, it's just that their GPUs are kinda shit so no one really cares.

If you mean SR-IOV, that basically splits one PCI slot into several slots, which you then passthrough to the guest, which means in theory it should be supported. At least that's how the networks are treated, sadly I have not yet been able to utilize it on GPUs :)
