Back when SM3DAS was announced, I thought that the lack of any major improvements was very fishy and immediately caught in that these were just upscaled roms on an emulator. Of course this ended up being correct. I'm getting a very similar feeling with the Skyward Sword "Remaster". Something about the models and textures looks very "Wii" and not very "HD". Is there any feature/aspect shown in the trailer that COULDNT be done with an emulator like HAGI?
