Yeah, that seems to be the only thing; a little longer to get the product. But...so what? I bought the 240W adapter for half price, so I'll wait a little longer. Worth it.
First thing I noticed is that it's quieter than my 3! Second thing is a lot more range, even with the base controller. The controls aren't much different except for the camera controls for the three lenses and the vertical shot feature.
I have one of those "ideal environments" that I'll try when I receive the unit. It's likely I'll upgrade to the new controller, but not this month. ;-)
