Why isn´t there a DMC game for psp?

I was just wondering since there is going to be a God of War game for the PSP

Why didn´t capcom came out with a Devil may cry game, because this is another one of the mayor franchises of the Sony Playstation 2

I saw on gamespot that there was going to be a game , but it never came out

Even now, it will be great to have a DMC game for the PSP

Maybe this has something to do with ghosts and alien abductions, cause those things remain unexplained too

what other games do you think the psp it´s missing?
