Well, i would love to have some sort of backwards compatibilty on the Switch, but as more as i think about it, the less are the chances for it to have compatibility with the Wii U library. It would be hard for it to have backwards compatibility with wii u games and I think it could be because: No dual screens. To play in your tv, the Switch needs to be in that dock thing, so no secondary screen or off-tv play for wii u games (though most wii u games plays fine without the secondary screen) No optical disc drive As seen on the reveal trailer and screenshots, there seems to be no optical drive for discs. How could we play wii u games on it? Unless they re-release them as digital downloads. Having them kills the whole point of Switch, playing in home and on the go. Yeah, how would you be able to play wii u games on the go if it somehow ends having a optical drive? Again, unless they re-release the games it could work. Different architecture I'm not 100% sure about this one, but you know, to have backward compatibility the console itself needs to have an arc similar to its predecessor and the wii u relies on PowerPC while the Switch doesn't. Well i can't think in more reasons but that's mostly it. I guess the chances for 3DS backwards compatibility are higher than with the Wii U one. What are your thoughts?
