Yeah, those comments seem to be tongue-in-cheek. I'm more concerned with the apparent "Let's cobble together bits of every system!" approach.
Say what you like about fourth edition, it was well-designed. They started from the ground up and built a system that was coherent, cohesive, and worked as a unit. It wasn't my personal cup of tea, but I could respect the work that went into the design.
Fifth edition looks like it has no underlying design philosophy at all. I really hope that's not the case, because, "Let's let people vote on what they want to see included from older editions" is NOT a good way to design a game.
