RVD could stay in the WWE and get a big push if he wanted, but he's so pissed about the ECW thing and the fact that they won't give him time off that he's not going to.
He's not going to lose money in TNA. He'll get a pretty decent contract, plus there'll be a lot less travel expenses for him to pay since, he'll only be traveling 4 to 5 times a month. Meaning he'll be able to be home, run his shop, and be with his wife a lot more.
