"D-Wave intends to also build gate-based hardware. Baratz explained that he thinks that optimization is likely to remain a valid approach, pointing to a draft publication that shows that structuring some optimization problems for gate-based hardware may be so computationally expensive that it would offset any gains the quantum hardware could provide. But it's also clear that gate-based hardware can solve an array of problems that a quantum annealer can't."
