Really, I think the industry needs to stop all of this "this will be the future" crap based on what they want to develop and shove down people's throats. I think what they are actually saying is "casuals really like motion controls, so we want to develop all our games for them, so you core gamers who do shooters and stuff had best get used to the idea". The idea to indoctrinate people to think it's inevitable and get used to the idea, as opposed to you know, maybe not going along with it and not buying the products or whatever.
I say this because all of this misses an important key element, motion controls involve getting up and spazzing out in the middle of a room. Sitting back in a couch/on your bed/in a nice comfy chair with your controller and shooting stuff in a game is relaxing, getting up with a light gun and aiming it at the screen is considerably differant. What's more hardcore gamers who play 12 hours a day or more in many cases are NOT going to want to stand there with a plastic gun in the middle of their living room for all of that time. Heck, their arms are going to get too tired for all that hardcore gaming.
Then of course there is the issue of space, like it or not, hardcore gamers are frequently pretty solitary. Hate to say it, but a lot of the stereotypes are true. Chances are they have their system set up in a place where they won't be distracted like a basement, their bedroom, or heck, in their (probably small) apartment. One of the issues with motion controls to begin with is the issue of space, and while it can be argued that for a "family entertainment" type game they might put it in the living room and move the cofee table out of the way to play or something like that, with shooters it's differant.
I mean honestly, do they think that these guys, even the kids, are sitting around in the middle of their living room with people around shooting off their mouth and saying the crap they do on these voice chat servers? Trust me, that "trash talking 12 year old" or even the older kids and adults aren't doing it in front of their wife/girlfriend/parents or whatever. Heck in the case of the 12 year old most parents would ground them from the system if they heard it (and honestly, I've listened to things like this happen with Vent when a parent walked into Jr's room, and heard what kind of things he was saying to the rest of us while we were PVPing in WoW about the othr side, and this tends to be mild since we're all on the same side as opposed to someone trash talking the other side directly).
Then again, while half offensive, and half worshipped, there is a lot of truth to the gamer stereotype even if it's far from exclusively true. Like it or not, a huge part of the audience for these kinds of games ARE the obsese, neckbeared, cheeto-dusted, game-fuel guzzling basement dwellers. Even those that aren't are playing to relax after work or whatever (and again want to play for regular multi-hour binges). Motion controls do not
work well with this crowd. How is the guy with the motion control going to be able to casually pop a chip in his mouth while having to constantly aim a lightgun, never mind sip the game fuel or whatever. Is the guy who worked all day going to want to aim a plastic toy at a screen for 4-6 hours?
My general sentiments are basically "good luck with that". Of course then again given the lack of anything other than whining among gamers
