Salaries are very hard to pinpoint since there are so many subjective considerations (house show revenue, merchandise sales, PPV appearances and buyrates). Your best bet is to try search engines, I think some people here are starting to get annoyed with all the threads asking people to look up facts and figures for them rather than discussing issues in wrestling.
Personally, I'd like to see them end the split. It was supposed to create new main eventers but it hasn't really. As long as there is a split then I recognize the need for 2 sets of Champions. However...one world...one world champion. Just my opinion.
