I think Metro is only published by THQ. I don't believe they own the IP.
Part of me wants to see this happen just for the internet backlash.
If Bayonetta 2 was anything to go by then some of those THQ IP's being Nintendo only will create some fun reactions.
The Metro IP is from 4A Games right, does THQ own it or only publish it?
If they own it then i definitely want to see the reaction that would cause.
Of course, you can be assured that Clearlake will increase its $60 million bid accordingly.
