Is that how you think game design works? Everyone works on programming, then they all move to story writing and dialogue, then to world-building etc? Of course not. If Kinect was to be implemented, then a dedicated team would be set up to handle it. They wouldn't say "Let's grab John from story-writing, Lisa from animation, Sam from world-building, and Jake from QA. They can divert their time to Kinect implementation."
Either way, I've given my argument for why Kinect won't necessarily be a bad thing, and why it certainly won't detract from the experience, only add to it. I can't say any more than that. Either people open up to the idea that change can be a good thing, or they stick to what they know, fearing and hating anything new. It could be great, it could be awful. The base game with controller or keyboard/mouse will always be there and always be great. We're talking about something extra here, not a replacement. Thank god game developers such as Bethesda are known for their innovation and for pushing the boundaries. If the majority of people in this thread ran Bethesda Game Studios, TES:V would look just like Arena.
Ya don't know how a company manage their resource, don't ya? Added to Scars Unseen's comments of thing, the Dev is still dipping into their resource pit and use whatever they can to make their game. It is worth mentioning there is a thing call time. They are making this game on a deadline here. These both are finite to the Dev in order to make their game. They cannot just simply do everything and not expect to cut corners every turn.
And as for ya eye opener, consider this. Since we are talking about extras, let talk about how it can screw up. Namely bug. One of the reason why I mention debugger in the first part is because Bethesda tend to be known for their bugs and can get away from it when it comes to scoring game. Reviewers know this. Fan knows this. Even their own company knows this. I rather Bethesda would at least go into making the game as bugless as possible rather then keeping the reputation of this bugfest they are known for. I can imagine that if they do use Kinects, I can picture that in some way, there will be bug in regard to adding that feature into the game and they would have to use up MORE resource just to sort it out.
And ya know, Bethesda pulls things, but not forward all the time. Morrowind to Oblivion, people complain a whole lots of craps as to what feature has been cut. Compare to Daggerfall to Morrowind, they went backwards in some cases. Too much complain lead to many "correction" that it was noticeable when they made Fallout 3 almost as close to Morrowind, but still suffer in the writing and lore department. Adding random "feature" does not always mean forward.
As for ya Arena comment, its more of an adaptation rather than just adding an extra useless things to it. They cannot just stay with the standard of Arena forever but at the same time, they cannot just forsaken their own fanbase just to impress a small amount of community by adding something that would be consider a waste to resource for those who do not use it.
Bethesda is on the list of developers/publishers that have pledged to support Kinect, so they will have experience using the hardware and software for it and all the QA that goes along with it anyway. Bethesda likes to bill itself as a developer that pushes the limits in game development so why not really do something different?
Pledging support does not mean use. It can be a publicity thing for all we know. I can picture that Bethesda might publish other company's game that supported Kinect rather than shooting their own foot and implemented into their TES Serie. Hell, Activision Blizzard is on the list of pledged supporter of Kinect. It is unlikely they would just put these support in say, WoW, Starcraft, and/or Diablo. WoW fan would complain it to hell, like they did with when they have to put their "real" name online at one time; Starcraft fan would complain that the other two campaigns are stalling because "Blizzard" want to add in Kinect; and Diablo fans already piss off that Blizzard made their game in colors of WoW, I don't think they would be happy their game is being pull more forward on time just to add that.
And like Bethesda, I can already picture that going the route of adding Kinect is equivalent to jumping into a herd of hungry, angry dogs.
