Yes, I would think that most of the teams participating in the Euroleague would join this venture. I am sure that some of the owners( such as Real Madrid, Barça, Olympiakos, Panathinaikos) would join without hesitation...

The brief thing I had heard included holding places in the league for some of the more popular existing Euro teams.

What I find exiting is that once this league is established the NBA can have it's version of the Super Bowl, which was original a match between the best teams from two different leagues.
