Gore-Tex Active Shell is a yawner....it's the exact same PTFE/PU sandwich they've been selling for decades only now they're using a wee bit less glue to hold the layers together so the breathability is a smidge better.....whooopee!
The only interesting development in WP/B is NeoShell (and maybe breathable cuben). Columbia's Omni-Dry isn't anything to get excited about. Columbia claims their air permeability is 100cc/min which works out to only 1/28th as good as eVent (claim: 0.1 cubic feet/min or 2800cc/min). Since eVent is more waterproof too, there's no reason to get excited about Omni-Dry that I can see.
In my experience, WP/B jackets usually fail because the membrane degrades or the construction was poor to start with. I have a 12,000mm jacket that has been unbelievably waterproof for years. I rode my motorcycle with it on for 5 days of solid rains at 60mph and never got wet. Accordingly, I think 10,000mm for NeoShell could be sufficient if it doesn't degrade over time. Also, it sounds like Polartec could trade off some off that air permeability for more waterproofness if they want. Something that is maybe 2-3x as air permeable as eVent (instead of 5x) with a HH of 20,000mm might be the ticket.
