The latest edition of the Wrestling Observer Newsletter (subscription required but recommended) has an interesting report on a meeting between WWE and Lucha Underground officials that apparently took place late last year:

There was a meeting in December between Lucha Underground and WWE officials, but nothing came of it. Some things were discussed regarding talent, but went nowhere. Vince McMahon wasn't at the meeting, but the key WWE people involved were Paul Levesque and Canyon Ceman.

That it was Triple H and Ceman in attendance does suggest that it had to do with talent, though, obviously, there are no details beyond that. Either way, it's an interesting development considering it wasn't that long ago that Chris DeJoseph, a writer and producer at Lucha Underground, claimed WWE basically "tried to shut us down" by signing top talent away.

Then again, as the report states, nothing came of it.

If nothing else, it's a story worth keeping an eye on going forward.
