Supposedly the 2000's are what they are looking at right now and there are 6 ready to go. If it's not the 2000's then something bigger. The people I was talking to said they have to find something in the 70ish seat range and that is the only draw back to the 2000's. Putting together the training program would be expensive and a paperwork nightmare I am sure but if they want larger aircraft they are gonna have to do it.
