My understanding of gallium arsenide MOS (and I could easily be wrong) is that its speed advantage for logic started running out at about the 0.35 micron (350 nm) node, which is where Vitesse gave up and very nearly went out of business. The future might not be silicon, but there's little change of it being GaAs.
Intel has recently been talking about using GaAs on future processes. Everything old is new again.
