johto was such a good region as well! I loved it so much and the remakes were awesome as well. it reminds me so much of japan, which is somewhere I personally always wanted to go to (but now I have) its a shame the metal and color forum is so inactive. I used to try to get it more active but it is soo dead there is no point :(
& I don't think it will be on wii u, cause they may be making a new console next year, also like you said with playtime, the market Is with the 3ds on that one. but maybe we will get a release like smash, both on wii u and 3ds, with the same feature ect.
