I see people asking this sort of question a lot - if you're serious about it, just sell it and get the camera that has the features you want. I had a 7d - shot with it for 3 years, sold it, got a 5dmkIII and am very happy with the upgrade, it just is a better camera in every way and IQ is improved besides the full frame advantage. I don't understand all these questions about "does it support the 7D, does it support x rebel..." why bother honestly?
