New Character Guesses

I think we have seen a lot of threads on who you want to see added, and I think it is probably safe to say probably 90% of those will be added, but I am more curious as to who is going to be free and who is going to be premium. Also can speculate as to who you think would be next.

I am thinking Ralph is destined to be a premium character, EA has to know anyone that is willing to spend actual cash is going to buy Ralph, well at least 95%.

Selma and/or Patti will be free, very possibly with the DMV
Dr Nick will eventually be a premium but I think he is a long way out
Dr Hibbert free
Smithers, possibly with the Burns Mansion I would think is free, and I could see this one being in the next update

Anyway, just curious as to others speculation
