I agree with you, I think, will come with a new form of poker, and it will become even more popularYup - NLH is currently without question the most popular game at the moment. Apparently it used to be an unpopular game compared to the other poker variants.
The reason for it's popularity would probably be due to televised poker events and the fact that it's a pretty simplistic game.
Fundamentally speaking of course because as we all know the game is very, very complex. lol.
Who knows though? Maybe in the future the more popular game will be a different or maybe even a new poker variant?
