This is a pattern for new consoles these days. The XboxOne, the PS4 and even the 3ds got lots of ports.
Heck... the PS4 is still getting some, like RE: Revelations.
So no big deal about it, I personally wouldn´t be interested in some of these games, because I´ve already played on the WiiU (like Pokken, or possibly Bayonetta) , but many people did not play them and will have the opportunity
Besides, there´s plenty of new games coming to the device,
