i think, sadly, that the people that will be attracted to the pdi are the ones who aren't good enough to succeed in the ifbb. if you can get top 10 at the mr o, what incentive do you have to go pdi? lee is an exception, but he's lee and his history with the ifbb isn't the nicest. financially the fed doesn't offer much to someone who can get into the top tier in ifbb shows and they certainly don't have the reputation of the olympia.
a pdi show isn't going to be paying over $100,000 for the win plus a vehicle for a long time. and even when it does, that show still won't be "mr olympia". the people the pdi will get will be those who for one reason or another can't make any money in the ifbb. until they start pulling really big names they won't drum up much support. and to pull the big names they need to have a hell of a lot to offer.
people want the pdi to succeed just because it's competition to the "evil" ifbb. but unless there's a gameplan that isn't just "be another fed" it won't go anywhere.
I respect your opinion here man.
You're right- the PDI will not attract the top 3 guys in the IFBB. But they may get guy #4

For the athletes- Unless your name is coleman, cutler, dex, or gustavo, you're not going to be earning 100k a year from BBing. For them it makes sense to stay. but since the careers in the sport are so short- a ten year competitive pro career is a rare thing- why not jump if you know you're not going to earn $10k in your whole iFBB career?
For the fans- it's NEW! Imagine going to a BBing show and NOT KNOWING WHAT TO EXPECT. How many fans know what every O will be like? You know who the top 10, top 3 will be. You know who will be there, what the politcal banter will be. This is NEW. We don't know what shows will be like. Wayne's talking like it'll be way more fun and exciting than ifbb shows, and the athletes have all sorts of cool stuff planned!
Gameplan- aesthetic, guys that look like fans/everyday public want to look like, and more exciting shows.
