Well all I can say is personally, I hope it doesn't move to "75%" foam or whatever the saturation point may be. I dislike anything foam and far prefer a heavier flying airplane.
Something about foam that says "cheap" and more of a toy. If there are a bunch of foam guys who love electric planes... all the best to them, but I'll take a gas powered composite or wood plane anyday.
It's not a warbird fly-in without the sound... how boring would that be to have a gaggle of electric foam planes flying around? Boring. Quick way to kill attendance IMO, and push things closer to TOY and not hobby territory.
