How do you think it will improve the gaming industry if that were to happen?  It comes up so often that one of the consoles is "d00m3d" and then there are the cheerleaders hoping that would happen.

So this thread is to give a good reason why the industry would be better off without one of the big 3 or if only one company had the only console / portable in the industry?

It won't improve, I like the competition, competition forces people to get their act together.

Competition helps the industry thrive.

Industry is better off with any any publisher/Developer that tries to Manipulate consumers or inacts anything that does benefit the consumer before all else, for their own agenda's.

Just like the market in general, more competition is better. I don't like Nintendo but they need to stay to keep the industry going forward.

I would actually like a 4th console like a proper Apple home console or Samsung or something.

I would like Sony and MS to leave the video gaming business. Why? So that gaming is left to companies that are (or, rather, have to be) entirely devoted to the industry. Stuff like Sony sacrificing its position in video gaming to help gather support for Bluray makes me realize that they have other priorities.
Whatever Nintendo does is what is, or at least what Nintendo believes is, good for gaming as a whole (as in, counting all those evil loserish casual grandmas and little kiddies). Sony and MS, on the other hand, may knowingly do something that is not in the industry's best interest because it's still beneficial to them for their company's other sectors.
Then again, it may just be that I'm a Nintendo fanboy who closemindedly disregards what the competition has to offer and wants them to burn.

Also, I really don't buy the "competition is good for you" argument. Nintendo wants to be successful and is largely unaffected by whether others in the industry are profiting or not. If left on their own, they'll keep on expanding the market, not rip off existing consumers. Offering a better deal is beneficial to Nintendo itself since it'll get them more consumers and, eventually, more profits. That's how I would see it, at least.

I just wanted to say for the 4 of us (they know who they are) ..we still believe in a Sega comeback.. B_E_L_I_E_V_E!

Calling doom is different from wanting them to leave altogether. We just want helpless irrelevance

I want SEGA to come back and take Microsoft out of the industry, Microsoft can migrate back to the PC and my lord and saviour SEGA can return.

i thought it was the MEGATON! thread
