It's more than marketing hype to run brushed motors, there is a major benefit to be able to run brushed and brushless on the same esc. Talk about a pain in the ass if you want to practice with a maintence free brushless but are not allowed to run brushless in racing. Who wants to redo their electronics mounting twice a day? Besides for the guys who have super clean and well mounted electronics I know that can take a good 30 - 45 minutes or more. I'm pretty sure that this esc will perform just as good as a GTX with a brushed motor, as I can recall Charlie telling me at the Birds that esc is basically a couple of GTX's in the case 
. Even if it performed slightly worse with a brushed motor compared to the GTX, I'm sure the average race couldn't notice, its a top of the line speed controller, how much worse could it perform?
When soldering to a brushed motor I'm sure that you could just solder say the yellow and blue wires to a stripped section on the red wire like an inch away from the tip. That way if you just plan on running brushed motors for a while you only have to solder one wire directly to the motor. Skuba or Charlie correct me if that wouldn't work properly though.

That's true about switching motors so it could be an advantage for those that race at track that don't allow brushless. My thought has always been that since brushed and brushless motors drive differently that your practice is not going to be at it's maximum benefit if you are practicing with a brushless and then have to switch to a brushed motor to race. that's not going to be a good option for top competitors. Also it weights more, but if you are already underweight than I guess that doesn't matter.
One aspect of programming I would like to see in the brushless is an Amp/RPM curve to limit the incredible torque at low speeds. I think it might be easier to drive that way. And a true drag brake, not just appling a sudden brake at neutral throttle, that is not how brushed motors feel, they drag down even at part throttle. It could be a formula as simple as drag force % = 1 - (throttle %/normalizedRPM) where normalizedRPM is 0 to 100(max rpm).
And I think there are probably a variety of ways to get all three wires to the solder tab like you said, so you only have to worry about soldering one wire at a time. But I also find resoldering the three wires back into the brushless solder tab holes can be a bit tricky, especially if you have "crushed" the wires soldering to a regular motor. Maybe it is ok, to just "flat" solder the wires back to the brushless solder tabs? Any tips on how to make this operation easier? Maybe just use those round Jeti type single wire connectors and make a 3 to 1 adapter for the brushed motor and three single adapters for the brushless motor (that never get unsoldered from the motor)?
Oh and Charlie, I thought I saw somewhere there is a "core trade in" value for older Brushless SS ESC to the GTB, (with a charge of course) or am I wishful thinking?

Yep, just got a email saying mine was shipped.
Won't be long now.

tr1kstanc3: Thanks for the heads up just rang them and got my old order cancelled and new order created against the Nevada warehouse. Now I just have to sit on my hands for a week

By the end of next week, I'll be sporting the new brushless system. Can't wait....

Man, Charlie wasn't kidding when he said that capacitor is big. 
Did it come with Tamiya connectors or did you chop them off in the picture?
