Well, they weren't going to go HD if they were looking to cut budgets.
I thought the biggest issue with the show is Tre and Jean Marc. I couldn't stand those two anymore. And as well, the judges never really critiqued this season and would generally gloss over the dancers mistakes.
My other problem this year was running the US version slightly ahead but at the same time as the Canadian version. Overdose. I think they were trying to kill the show and what better way to do it than overdose the viewers. If it had high ratings they would have had to continue the show. Why they couldn't run the show earlier in the summer, and leave the US version to later summer I don't know unless they were trying to kill it.
