PIC Controller with VEXNet Module

Some teams are still using old PIC controller with VEXNet add-on module due to budgetary reasons as well as its higher controlling precision. Is it legal to use the PIC controller with VEXNet module in the 2012 VEX World Championship Event?

VEX-E,

Thanks for your patience. Yes, it is perfectly fine to use the PIC controller with the VEXNet module during the 2012 World Championship.
