added features doesn't make it a remake, remake entails that it was built from the ground up for the respective system. Port, they built it on the already existent game.
It would have been a business better decision for them to just push Xenoblades or the last story straight to the WiiU's launch, improve the graphics, full HD, utilise the control and have it available as download,. By improved graphic i don't mean a complete overhaul, more a half jump between the wii and current-gen systems.
