For a business that amounted to all of $113 million last year, e-books sure are getting a lot of attention these days. In just the past week we’ve had an announcement from Google, concerning its e-book e-commerce platform, Google Editions, a sneak peak at the new Plastic Logic Que and hints of a “dramatically different” e-book reader coming from iRex. This week, Barnes & Noble will take center stage with the unveiling of its much-anticipated branded reading device expected to look a lot like the new Alex from Spring Design.

That all comes on the heels of recent announcements by Sony, Asus and Interead of new e-book readers and Barnes & Noble’s previous unveiling of its online eBookstore. Some of the new e-readers aren’t even on the market yet, but with so many big players chasing little business, can a shakeout be far behind?
