Does anyone on here really believe that Vince McMahon would have his guys face off against guys from another, lesser company, and have some of them lose? I, for one, simply don't see it happening. Ever.
I can't see McMahon allowing any of his guys to lose to anyone who is a former WWE talent, especially someone who voluntarily left. Likewise, I can't see him allowing any of his roster members to lose to anyone who has consistently snubbed his company. And I can't see him allowing his guys to lose to someone who has never been in the WWE. Rightly or wrongly, it would appear that he sees TNA as being beneath his company, and I simply cannot see him consenting to anyone under his employ losing to someone who he feels is from a "glorified Indy organization" (not my words, just my speculation as to how Vince likely perceives them).
This would only leave the option of all the TNA guys losing to all the WWE guys, and I'm not really sure how this benefits them. Sure, a one time ratings bonanza, then back to reality again. Which would likely even further highlight their shortcomings on a go forward basis.
No doubt, any fan would love to see it happen. I'd love to see it myself. But I simply don't see it happening.
