Should I Transfer or should I stay? UNC vs. ECU?

Okay, I'm a freshman At East Carolina University, however entertaining the idea of transferring to UNC Chapel-Hill. I have a GPA of 3.4 in the rigorous BS in Biology, and plan to apply to dental school to become a dentist after my undergraduate studies are complete. UNC has the only dental school in NC currently but, East Carolina is scheduled to accept their first dental cl in 2011 making it the second dental school in NC. Should I stay at East Carolina where they may favor their own students, or should I transfer to UNC?
