I think you should wait to get your board until a new revision comes out. What if they add a bunch of RGB to the board in the next revision, you wouldn't want to miss out on that right?
I can't wait for the day RGB PCB becomes a thing. I mean seriously why not, we already have red, orange (think ribbon cable color), green, blue as standard colors, so just gotta throw in yellow, indigo, and purple and we're done. And then we can throw in black and white on top to truly complete the color spectrum. Can't believe no manufacturer has thought of this, maybe I should patent this idea...
