No, the big Capcom push on PSP happened before MHP took off. Then when everything but MHP bombed, Capcom just stuck to that with the odd side project here and there (Basara spinoffs, Last Ranker).
Capcom's DS support however was a step down from GBA even. Most of the ports/remakes (fighters, Megaman) went to PSP instead, Starforce was late in coming to the system (and never managed the success of Battle Network), same for ZX (versus Zero) and really only the Phoenix Wright ports did too well it seemed. Capcom did give the system a nice last push with stuff like Ghost Trick, Okamiden and Ace Attorney Investigations, but that was well after they'd missed the boat. Capcom's reluctance to really back DS with support was bizarre.
