Surround sound is not something new to games. Developers have been including it for a looooooooong time now.
Every game has to have its sound encoded for 5.1. Every game has to have its sound designed to be used in 5.1. Every game has to have its gameplay accounting for the existance of 5 discrete channels rather than 2. Those are all additional costs that exist for every single game that uses 5.1. Those are not reusable components.
No, it may not be as little as an rj45 jack, but hey... RJ45 is even less of a standard in homes than 5.1.
RJ45 is the standard for computer networking. If they have a network in their home, they have RJ45 somewhere. It may not be available easily from the spot where they put their Wii but those people would be using the Wireless, the RJ45, or not using networking at all. But nearly every single person who uses a computer network in their home, at some point in that chain, uses RJ45.
I know far more people with surround sound than with home networks.
Well, if they don't have a network, they aren't on the internet. Be it a single node LAN attached to the outer WAN or something larger, they have a network. And if they don't have a
broadband style connection (which specifically requires network hardware) then they're not putting their Wii on the the net anyway.
What the heck are you talking about another 5.1 device after their DVD player? If someone already has 5.1 one for their DVD player, then they already have the hardware. There is no "another" required.
Many, many, many consumer level AV receivers only support one digital audio input. It is only recently that the lowest level started having multiple digital (either coax or optical) audio inputs. Only have one input? Gotta buy another AV receiver or a switchbox to support more than one digital audio device.
Also... I think we seem to have different understandings of the word standard.
DVD's are the standard movie format now. Digital surround is the standard for them.
There are
millions of households with DVD players using plain old red/white/yellow composite signals.
To me, standard means either the default condition or so commonplace that it can be expected in the vast majority of homes. Standard would be a 24" or larger television. A base consumer level DVD player. Using a remote control. Cable/satellite TV. Things you would expect to find in the home of a 20 year old, a 40 year old, or a 60 year old.
When designing a mass market consumer technology you have to keep those things in mind. What is the standard of your target audience? Seeing as how Nintendo aimed at as many people as possible while still keeping the price at an absolute minimum, luxuries like 5.1 and HDTV simply weren't within the demographic parameters they were targeting.
They even
said that. They came right out and said that if you require 5.1 or 1080i then the Wii isn't the console for you.
