I am surprised they do not release a Wii Sports like game to take advntage of the motion controlers

Fighting games are surging back in both sales and quanity. That said ARMS is basically SEGA's Virtual On. While it is a fighting game it's also a semi shooting game as like VO you have to take aim in an arena.

Definitely has the potential to be as popular as 1-2-Switch.

Coulda, shoulda, woulda.

Yes, I havn't seen much of the game, because Nintendo hasn't shown anything besides 5 characters and probably 6 weapons. I only saw one game mode and that was 1 vs 1. That's it.

This game shall release in spring 2017 and we know actually nothing else about it, or maybe there really isn't anything else about it. Just like 1-2-Switch. A small and really expensive techdemo. So far, that's my opinion of the game.

I think ARMS is the next step that motion controlled games required. It's not just taking old ideas and updating them with more precise input. Making a more precise Wii Sports didn't improve the original concept. Designing a game from the ground up with precision controls and utilizing the feedback of HD rumble, they have made a game that is a fairly large leap up in complexity, while maintaining the simplistic and intuitive ease that was Wii Sports. The problem with the Wii Motion+ was they just made less intuitive Wii Sports titles, and even Skyward Sword seemed to have a lot of issue, it wasn't the right sort of direction for that game.

ARMS is definitely a good pitch on how to take motion control games to the next level. I also have found the response to be surprisingly positive, and I think it will be big. I know I'm buying it.

You're only highlighting exactly why it's strange. Mario Kart and Fire Emblem are launching soon just like ARMS, but it still lacks an exact date for a game releasing within two months. Splatoon 1 was promoted well before launch despite being an unproven new IP much like ARMS, so if they have similar faith in it you'd expect similar treatment. I think this either means nothing, that the game is delayed, that Nintendo doesn't believe in it, or that there really isn't much to the game.

MK8 is launching this month so make sense to have launch date, ARMS is Spring game that basicly means anuthing from March to June,and Nintendo usually don't have exact release date so early before launch. Nintendo is taking game after game and focus game after game (only Splatoon is here difrent) after MK8 is out they will start promoting ARMS. If you pay attention you will see that they just recently started promoting MK8D. Splatoon was totally different, it had test fires and seems that want be case with ARMS. I really don't see anything strange with ARMS, after April we will see start seeing more  promotions.

Two months is so early to you? I guess that explains the difference in views here, aswell as considering June a Spring month, but eh, you don't see anything strange, that's fine. 

Like I wrote, MK8D just recently started to recive promotions, its obvious that Nintendo knows that Zelda BotW will be for quite time biggest system seller. Spring ends on 21. June (starts 20. March and ends on June 21.), so yes, June is also Spring month, actualy 2/3 of June is Spring, thats clear fact.

EDIT We having ND in two days and we most likely getting ARMS release date.
