We’re just hours away from Sony’s big Google TV unveiling where we expect they’ll announce four initial models with the platform embedded (ranging from 24 to 46-inch models.) Sony’s getting a little head start with developer sign-ups, however, as we’ve just learned that they’re accepting registrations for the developer portal now. There’s nothing to actually be had there at the time of this posting, but we suspect that’ll change before the day is over. If you’re a developer, go ahead and sign up now.
