US Nats becomes a non factory supported series
Top US riders ride SX then MXGP's with factory support
GP series has 3 rounds in states at beginning, mid & late season.
Each US round at diff corner of states to allow more people to reach a US GP
Each US GP would be the time for US top national riders to see if they can compete at highest level as wild card
USA could then fight for a world mx champion which would excite the fans to support the sport more
MXON date would be consistent for everyone
