If you look on the AMA website the Interim voting results have been posted for the cross proposals, all of them have been accepted except for one.
https://www.modelaircraft.org/files/CLSC2014InterimVote.pdfAll of the main proposals were accepted, this means that 1/2a scale and Authentic scale would become an official event. Designer Scale would be eliminated. Authentic Scale would replace F4B at the Nats.
Be aware that there is also a line diameter change with the new rules, below is a summary of the line diameter changes for multi-Strand lines only. Be ready next year for the new line diameters when 2015 starts.
Keep in mind these are not valid until they have gone thru the final vote and the rules are written for 2015. Look in Section 15-4 in the new rule proposal for the new line diameters.
