Big Dave is listening to outside offers and it should be noted that there is interest on the part of TNA. However, the belief is that it is highly unlikely "The Animal" would jump ship to the competition since they would never be able to offer him anything close to what he's making in WWE, which is in the neighborhood of several million dollars per year. It should also be noted that Dave is a big spender, has tonnes of cash and according to one source 'lives like a rock star' with a high quality house, several fancy cars, and more.
What Batista is willing to accept will probably be largely dependent on his other opportunities.
Is it a case of “what else is he gonna do?”
Or, does he have the ability to strike it on his own?
If he did - in fact - leave WWE over this movie dispute, he just may take whatever TNA offers him unless his agent has some big plans outside of wrestling already lined up for him.
Don’t forget, too, that Dixie has been pretty accommodating with her (especially, bigger) talent - much more so than Vince.
TNA knows they can’t compete directly with WWE salaries, so they offer other incentives to sweeten the pot.
Dave may arrange for lower pay, but with a lighter schedule that would allow him to pursue other ventures
(like acting) while working for them - I’ve read of similar deals for other main-eventers.
