copy n paste it

I think Nintendo would go to HD before 3D, they said since the Wii launched that they werent enough HD tv's in the wild and their are even less 3D tv's

Of course it will, it must be a really simple thing to implement on new machines... but Iwata is wise, it'll have to be more than that to be a success - or else a Wii HD will be just like a PS3.

Given that multiplats will probably be supporting 3D by then, and assuming the Wii HD will be similar in power (or even stronger) than the ps3/360, it would be silly not to include it from the getgo.

Even if they didn't include it at launch, they could easily enable it via a firmware update ala ps3.

The problem of doing it by firmware update is the capacity of the console generating 3D graphics: like PS3, they are downgraded when doing the double images. If 3D is to be implemented in their next console, it should be planned since from beginning to include it.

True

Nintendo is incredibly smart breaking the IQ scale so they know what is best anyway.

Why not go both HD and 3D and realease it in 2012 - 2013 , by then more people would hve bought 3D TV's.

Well I imagine like what they did for the 7th gen release the handeld then 2 yeats later the console.I think thats what they will do.

killzone 3 doens't look downgrade, depends on the developer really.
