I think overall it's a decent effort by the league to cut down on flopping, but since they won't be called or reviewed during games, critical flops/subsequent fouls that sometimes affect the outcome of games, will unfortunately still be very much a factor.
Clearly, if a player has the choice in his mind of using a flop to make a critical difference in a game, and taking the chance of getting fined, they're going to flop anyway.
The long-term effect will be interesting, but it's still a post-game, post-outcome matter, and will change very little on the floor, IMO.
Pretty funny clips, though ... love Tony Parker's and Reggie Evans', but Chris Paul gets the Oscar.
