Is Future the new T-Pain?

T-Pain has been absent lately, I guess his time is done. Future came in to fill the void of the auto tune dependent feature rapper and he seems to be handling himself well. It just goes to show that in the rap industry you could have a successful 5 year tenure by being more of a personality than an actual MC. It's pretty sad but true. And if Future is the new T-Pain who did 2 Chainz replace?
