Well WWE put so much money in NXT it wouldn't make sense to just drop it.
I don't think they should be trying to be competition to ROH, who like OVW produced a lot of talent for them.
There's a lot of guys in NXT that are there that don't need to be there. They should just be brought up to the main roster right away.
Will all the popular international and independent talent gone from NXT it would cool down a lot and it wouldn't be as popular anymore. But then it would become a good environment to develop guys. And that's what NXT should be all about.
