Yep, another thread, but in all fairness iPhone vs. Nintendo/Sony seems to be popular news at the moment, everybody has to have an opinion about it.
Personally (you can check out my profile to see where I'm coming from) I don't think Nintendo has much to fear at the moment. The iPhone is a lucrative market for small developers and small projects, but even the most sold game thus far has brought in only about 4 million of revenue. The total market for games is not yet that big, though I can't give you any indication of how big it actually is. My own guesstimate is somewhere around 50 million revenue for the devs so far, but I could be very far off. If I'm even in the ballpark, that kind of market can not support Nintendo-like games, even very casual ones.
Then again, the iPhone platform is evolving at a rapid pace, and the things mentioned in the article may well prove to be recipes for a greater success.
By the way, I think it is kinda funny how people complain how difficult it is to get your app to get noticed. Isn't marketing something nearly all succesful companies do? Nobody can base their business on word-of-mouth and viral marketing alone, that's just not a viable plan for the long term, yet it seems to be what the majority of iPhone devs are doing.
