Seriously, all these questions concerning these boxes can be prevented if someone just made a detailed post explaining the differences between them.
For crying out loud, what kind of company is this. For that many TP, I expect to know exactly what I'm buying and what the differences are. I want to know if sources of extra experience stack with the new stone, does it continue with the old one. Are both the stones changes from 7-15, or is it just the new one. Are there any bugs associated with the new stone as a result of coding the new one.
