I feel like this is a down year for players switching sponsors.
The best bits of news we have related to the topic are Paige Pierce being non committal to Prodigy and Innova thinking of dropping Patrick Brown because he has had a few outbursts.
There are going to be big announcements made in January, just as Chuck said.
Please don't oversimplify PB being dropped (allegedly) to a 'few outbursts'. Those are just the bits that make their way to the publics attention.
