Wow this is a great idea. I do have to say I'm disappointed, but not surprised, that none of the bigger brands in power tools look to be participating.
The only name I recognize there is Bosch, I've never had any of their tools but my perception is that they are a mid-tier brand. It would be great to see players like DeWalt, Milwaukee, and Makita do something like this.
Bosch segments its own market into the "green" and "blue" parts, the latter being for professional use. They're very well-made and costly, on-par and competitive with the other brands you mentioned. But of course they are not in this Power4All alliance thing and are incompatible with the "green" consumer stuff.
