Initially, I thought it was just a cost/benefit analysis.
Then, I remembered back when Tre broke down the costs of a webcast/PPV- it's really cheap. So that didn't make a lot of sense, unless they were losing money on their PPV advertising.
So I thought about the PDI. I've heard about a few of the guys' routines, and they're going to involve acting, music, props, creative lighting, maybe even a little pyro...
All kidding aside, it's going to make the Olympia look like a 3rd grade science fair. So maybe the IFBB doesn't want to have to follow an amazing PDI show, a month later with a bland standard O, predictable finishes, and no challenge round to make things controversial.
The IFBB might be a lot more nervous than they're letting on.
