When product development is just driven by marketing it just gets funny at some point. Gillette is saying now 5 blades are the holy grail for wet shaving.

Update:
Gillette Fusion in Stores Now!

Gillette launches the Gillette Fusion and the battery powered Gillette Fusion Power at the same time.
From the press-release:
"The Gillette Fusion features a breakthrough 5 blade Shaving Surface™ technology on the front of the cartridge, with blades spaced 30 percent closer together than MACH3 blades. The combination of adding more blades and narrowing the inter-blade span creates a "Shaving Surface" that distributes the shaving force across the blades, resulting in significantly less irritation and more comfort. The Precision Trimmer™ blade, a single blade on the back of the cartridge, allows men to easily trim sideburns, shave under the nose and shape facial hair with control and precision."
The Trimmer blade sounds quite useful though.

The new Gillette Fusion 5 Blade razors will be available in Q1 of 2006. Pricing will be $9.99 for non-powered version, and $11.99 for powered.
Tons of material on the Gillette Fusion site. First seen on ShavingStuff.
