I've got Coronation Ace Revolution. Before I bought them my supplier checked with John Wilson and was told that standard blades in my size were 660g and Revolution blades were 600g - 10% lighter. Not really noticeable. I haven't noticed them damping my landings but if you only leave the ground by a few cm then you're not going to.
The Revolution blades were designed for lightness to help with triple and quad jumps. It's not something that is useful or helpful for skaters at lower levels. Jumps are best learned and mastered in traditional blades, keeping the little boost for when it's really needed, ie for triples/quads.
Adult skaters, however, want all of the shiny things and will happily argue for them so it made good financial sense for JW to extend the technology to the hugely popular Coronation Ace for those adults who didn't have the ego to insist they needed elite equipment.
I never recommend the Revolution or Lite versions, unless the skater physically needs lighter equipment (I've known a couple of skaters who were so tiny that they struggled with traditional boots and blades) but learning with the traditional blade structure makes it far easier to learn catch foot moves, especially spins where it's hard enough trying to locate your free foot without the added intricacy of getting a grip on blades without decent space to get a hold!
As far as I'm aware, Revolution blades aren't designed for a cushioning effect, although I could be wrong on that. These new blades, however, are designed to cushion landings and hopefully prevent stress on the landing leg.
