That's the trick of course. In 2 years time they will introduce the flexball in to this new 2 blade revelation claiming this that and the other, then in another 2 years after that another blade in to the equation etc etc etc. In 10 years we will have either the latest 5 blade is best razor or may be the revolutionary DE with interchangeable blades.Looks interesting. They've dropped the Fusion flexball though. I was kind of hoping this would be the Fusion flexball design with less blades and cheaper carts (at least Wilkinson Sword with their Hydro give you the option of 3 or 5 blades per cart). Looks like you'll still pay a small fortune for the carts, and the cart itself looks rather chunky for just 2 blades. Not great for getting under one's nose.
I will give them an A for effort.
