In 2015, DKC TF, hyrule warriors, bayonetta 2, lego city, pikmin 3 and zombi U should all reach 1 million (even if they must include digital). Although zombi U and pikmin 3 may have to wait untill late 2015.
New releases that will definetely reach 1m in 2015 are Zelda and star fox. New games that almost certainly will reach 1m are splatoon, mario maker, xenoblade x, yoshi wooly world and mario party 10. Kirby and devil's third may do it, it's hard to know. If we get games like pokken fighters, animal crossing and metroid in 2015, they will easily sell 1m+ too.
The yearly skylanders and just dance might do it if they keep the current yoy increase pace. If third parties remember how to do their jobs properly, at least some of their multiplats will be million sellers.
I guess among current and future games, at least 21 will be million sellers in 2015.
