You might have copyright/trademark issues... you'd have to look into that. Unless you've got truly premium domian, the domain alone isn't going to pull big bucks. If you develop a working, profitable site, then they're worth something.
If you develop them and make money then the copyright issue will come to the fore quicker as it is easier for copyright holders/TM holders to claim the domain from you if you are trying to benefit financially from the TM name. So dont develop it, worth reg Develop it for money and get it taken away for zero Either way, sorry, I dont think so imo.
