There is already something that is analagous to this situation. PC and consoles.
A pc is a multitasking device that people already have that plays games with a default control set. Consoles let you play on a bigger screen with better controls and are simplified to a single version that all the games play on. Its an extremely similar situation except the i stuff has almost none of the kind of games that acutally sell on the current ds. If the 3ds has the games people want to play people will buy it. Its that simple
Complaining that the online store will have to be downloaded (probably on launch day) is bullshit. It will probably be available on launch or close to it so this will have almost no effect. With his emphasis on DD he is like a lot of people talk about DD being the future; they forget that the future is not now. It is in the future because it can't happen now for whatever reason.
I also see big potential problems with a 3d touch screen. I get the feeling the 3ds has the 3d only on top for a reason.
Its a good troll. He basically says how amazing the 3ds and then says what if, what if, what if, what if.
The Wii succeeded in being the number one console but largely failed in being a "serious" gaming machine. You gotta take what you can get, and sales for any reason are still sales.
I believe it is currently the number one console of all time for this time in their lifecycles. Don't put some bullshit "serious" moniker after it.
