Those are not reasons. For one thing, it's a huge spin to call copycatting motion controls as some kind of knock to the when when those came AFTER the industry bashed motion control as gimmicky and a fad.

Having virtually no third party support whilst having no major first party titles anytime soon isn't a reason?   Nintendo is notoriously slow in their development cycles,  with no third party support you are witnessing the same effect that N64 and Gamecube ran into.   You don't think consumers take this is into account?

  It lacks any form of compelling online gameplay  (Just another feature lacking when you can get a 360/PS3 for comparable price).

And if you're truly interested in Motion Control gaming in some fashion,  you aren't FORCED to purchase a Nintendo Wii. 

These are all reasons, combined with the fact that the graphics in the system are incredibly aged and you have a product that is certainly in the process of dying.

No one cares (Except the Nintendo fans) that Microsoft and Sony called motion controls Gimmicky.  Hell, at this point one could actually make a case that they were in fact gimmicky.  (As we see the Wii free-falling)  and many of the Wii's best games really had limited functionality with Motion controls.

"Having virtually no third party support whilst having no major first party titles anytime soon isn't a reason?"

1. It never had it even when it was thriving.

2. Anytime soon just means not for now.

"Nintendo is notoriously slow in their development cycles,  with no third party support you are witnessing the same effect that N64 and Gamecube ran into.   You don't think consumers take this is into account?"

Did you even read the OP? This thread is not about the sales decline. Also, Nintendo is not the only slow one, as a lot of major games on the other systems took way too long to make.

Even with those studios they haven't even got out a Wii Zelda yet.  Not to mention the other classic franchises with no iteration that Nintendo fans wanna see again.  

I only really see maybe Capcom giving them worth while titles( saleswise in japan and the west) and that's mostly because of their history as only RE4 is the only game that comes to mind that did well on Wii. Is delegation sufficient to persuade the Western 3rd parties who have had little success on the Wii in the first place to give them exclusive content? These games are gonna be expensive at PS360 level of graphics and whatnot.

I do understand your point but it just seems to me that somethings gotta give.  They have to get more studios or start paying out for exclusives the way M$ and Sony used to. 

@padib  but wouldnt the "serious gamer" have bought a PC PS3, 360 already??? IMHO there is no reason that if your a serious gamer you would only have a WIi. Hell if your a serious gamer you would have more than one gaming machine. The writings were on the wall when it came to WIi and a certain type of games they would get, I knew from day 1 that they werent going to get the GTAs, RE5s, DSs, etc. Thats one of th reasons why i had to get PS3, for great 3rd party support. thats just me.

I agree with your gimmicky part, but as a fan of all of Sony's consoles thus far, i could really give a damn what they say about the competition, even though i dont agree, there only responsibilty to me is giving me games i want to play and thats exactly what they have done for me. Sure its "bad" but there rip-off actually delivered on accurate controls day one so i would say thats "good"

Although you obviously have a different context, that sentence showed what was wrong with the Wii support from third parties and Nintendo. What I mean is for the most part, they outright refused to do that. Now any reasons have the simple problem that it was the artists deciding they know better than the patrons (which is a modern myth about many forms of art, but it doesn't happen that way in history).

And when Sony and Microsoft decided they knew better, their systems were having trouble, and they had to work for the customers again to get some momentum back.

^^that true, when i said serious gamer, i was talking more in lines of the amount of time and amount of games that are bought. and Sony PR does blow, but it has gotten a little better

1.)   You're right it never has had it.  It's just always had the possibility or chance of having it in the future.  To anyone who owns a Wii now it's very obvious that it will never have good third party support.  It's worse now later in the generation to not have strong third party support than it is early in the generationm,  every company has already released their 'big hitter titles.   Waggling just isn't as cool as it was 4 years ago and every competitor has a waggle equivalent.  

2.)  Anytime soon means for quite some time and looking across the horizon, it doesn't seem like it's going to get much better.  There is a reason we're hearing rumblings of a new Nintendo console .   That's because their forecast ahead is looking more and more grim.

This thread isn't about the sales decline? I'm sorry then what the hell is this thread about?  From the OP : 

Some are declaring the Wii dead or dying. Not only does that ignore the sales are still respectable, it also pretends that solely because the new system is announced, that spells the end for this.

If you have a fully functional and operational brain and follow business (In any avenue)  then you know that no-matter who it is or what company it is,  they all engage in this war of public relations words.   They say things to discredit the other companies solution or ideas in an effort to do more business for their company.  It's how the world works.   This is obvious what was occurring because Sony was doing the Eye Toy on PS2 and Eye Toy / Sixaxis on PS3.   So putting weight into PR battle words is ludicrous. 

1.) Yes the market is saturated but that didn't stop the PS2 from continuing to run rough shod over it's competitors. 

2.)  Nintendo would be happy to release ANY hit at the moment.  They just aren't releasing compelling software at all, regardless of the target audience.  That's a big problem.

3.)  Obviously, I wasn't referring strictly to the Wii's best games as the ones with the highest sales.  I was more referring to just the flat out 'Best quality games' in my eyes, many had no need for motion controls and they were just really tacked on in most ways.

I think Motion controls are fun and have their place but when you really look at it, it kind of is a gimmick that still has a ways to go before it's truly viable in the manner that it is meant to be.   I really didn't enjoy certain games with their inclusion of motion controls (Which is where the gimmicky tagline comes from),  while others it really enhanced those specific games.

Definitely dying. Dead, No. Dying, a definite yes. Most of the Wii systems in my friends houses haven't been touched or turned on in months. The one in my living room is going on about 8 months without being turned on. It is more just there as decoration to add to my gaming Library. It seems this is the case with most Wii systems these days. Still you are going to have your 12 year old boys/girls begging their mom for one, and soccer moms throughout the world buying them. They take it home, play it once or twice, and then it sits... and sits... and sits... The Wii is dying, holding on by a thread. Might as well be dead.
