Which leaves us with new Nintendo console, the star of the second screen movement. The principal difference here is that the tablet isn't just a value-added extra as it is with the Xbox 360 and PS3/Vita offerings - it's the core of the experience, with the most exciting, versatile technology. Hands-on with Wii U, we were drawn to the concepts Nintendo came up with and surprised by how robust the third party exclusives were. PS3/360 conversions with tablet functionality tagged on proved to be somewhat less compelling - and this is probably our principal worry with SmartGlass's gaming potential. If developers aren't going to make money with it (as they might from Vita double-dipping), and the applications are limited to value-added extras only, will SmartGlass attract the resources and ideas it needs to be successful?
