A developer, who has worked on a handful of racing games including the Test Drive series, updated his LinkedIn account resume. Two of the titles were unannounced titles both were for Xbox 360 and PlayStation 3, but one of the titles was also listed for another platform listed as “Wii2.”
Whether or not this is a typo or a leak is unknown, but it does point to the possibility that developers may be looking towards a next generation Wii.
If it is true, I doubt we will see anything official any time soon. The Nintendo 3DS was just announced and I’m sure Nintendo will probably be focusing on it late this year and early next year to make sure that the platform sees a successful launch.
