It's true, online gaming is clearly in its infancy at least as far as consoles go. But I believe that there are special circumstances at work in this case. Personally, I wouldn't be half as interested as I am in Xbox (which isn't very much at all) if not for Xbox Live and what it promises. At the end of the day, Live itself suffers due to a lack of truly great exclusive software titles on the machine. Watch and see what happens when Halo 2 rolls around and it starts selling like a godsent cure-all, it will undoubtedly take Live with it. The reason being that the Halo sequel is the only sure-fire triple A title joe schmoe can name for the Xbox, that also happens to ooze further potential thanks to the features the Live service affords it.
Unlike Microsoft, Nintendo has Halo-calibur franchises up the wazoo, that's how I see it anyway. Every single franchise title they have is simply brimming over with potential for online features. Where Xbox Live is a match to a pool of stagnant water, a Nintendo online service is a flamethrower to the lake of gasoline that is their game library, if that makes any sense. Now, it is smart to ease into something like this, everyone understands that which ever way you look at it, connectivity is a costly investment. Sony and Microsoft can much more easily afford to be brazen about such costly ventures, so it doesn't surprise me to see them emphasizing it over Nintendo. In the next-gen though, the pressure is going to be on. Those two machines will hail their next-gen connectivity features as a second coming, and most people will buy into that. They may not take full advantage of it, some if not most may not even be able to use it, but they will at some level factor it into the value of the product they're buying. When they look over to Nintendo and find a major difficiency in that area relatively speaking, well chances are I think a potential customer will have been lost at that point.
Though the market may begin to expect these kind of features in earnest next-gen, I wouldn't say Nintendo has to follow the same pattern as their competition to be able to compete, not at all. As I said in another thread, there is plenty of room for innovation in the execution of all this connectivity business. I'm confident they can come up with a way to make online gaming profitable. But.. I believe it'll take market pressure to force them to take the plunge, and absorb some of the risk and/or inevitable initial costs. I think that there are perculiar circumstances associated to the prospects of online gaming via console. Yes, there aren't a lot of people engaged in it this generation, even fewer people who actually have the option to do so. But I believe this is one of those things that can only truly grow, expand, and mature from the end of the content providers. If the content is there, if the service is there, eventually the people will come and yes they will pay. I think Sony and Microsoft see it this way, although of course their perspective is skewed by what they can afford to offer. Well, if all broadband meant was faster loading webpages, then that quarter+ of north america currently subscribing to it wouldn't bother with it, and the percentage of usage would be far less. I feel that of all the gaming companies, Nintendo should be the one helping to aggressively usher in a golden age for console gaming thanks to online playability and services, simply because they tend to do things in interesting ways and of course because their games above all others as I mentioned, are overflowing with the potential of it all.
Will Nintendo listen to this sort of take on things? Nope, no great insight there, that much is just obvious. Did they listen when designing the cube? Not really, but at least they listened and responded more than they did in the preceding generation, if not to any person then at least to the circumstances at hand, so there's hope in that.
