I am more excited for the Pikmin game than the Mario game to be honest. And it'd be interesting if somehow a legitimate character other than Olimar can show up that is distinct enough to even be another Smash Bros. character. Or even have Louie do things that aren't the exact same things Olimar.
Now that is something I wanna buy.
That would be awesome if they do it like the first game, where you have a limited amount of days...
...But this time with seasons! YES! Once your spaceship crashes, you can go to different routes since the day 2, however, every 4 or 5 days, the season changes. Meaning, there's a good replay factor to it (you can beat the game many times in different ways, enjoying each season in a determined area).
Spring, summer, fall and winter never looked so pretty!
Spring: Beautiful flowers of course, most of the paths would be blocked by wines and little gardens. Also, a lot of spaceship parts would be hidden by leaves. So you gotta search!
Summer: 2 days with bright sunlight, where everything is easier and have a lot of open paths, while it has 2 days of rains, where most of the pieces locations would change because of flood/water streams carrying it somewhere else.
Fall: It has its own characteristics with certain parts totally hidden by leaves, pitfalls where you can lose a lot of your subordinates, powerful winds that sometimes can make your Pikimins to fly away and get lost so you would need to find shelters to hide from the wind with good timing.
Winter: Most of the dangerous creatures are hibernating, but you will need a lot of puzzle-solving and have a lot of a certain type of Pikimins cultivated, maybe add in light Pikimin who can walk through frozen Lakes without breaking it. Pikimins who can stand the cold and most importantly, with all the snow blocking your paths, you need to get a good amount of yellow ones to bomb the snow clusters.
Ah, one can dream...
