Just because you could operate superconducting qubits at high temperature doesn't mean you would. By far the biggest problem for qubits is noise, and raising the temperature would increase noise. I won't claim a high Tc superconductor can't help... but my gut reaction is that it's irrelevant to the actual engineering issues as they currently stand.
