Is there a new line of subs or upgrades to the subs coming out and if so when is the expected date ?

I ordered the M80 a month later the M100's came out.

I don't want to do this again, I plan on ordering a couple EP500's but if the new line is coming will wait. Chances are I am going to order after christmas anyways.
