@bold. That can all be done on the same console. It's purely about marketing if technical upgrades are totally out of the picture.
If a competitor offers the updates on the same console, doesn't that invalidate the need for a brand new console, unless there's some other considerable upgrade that requires a new machine (such as a performance upgrade due to better computer components)? So a console in your perspective is purely artificial and has no reason of being, since a competitor in that case could easy cut over your offering by making it an add-on and saving people the need to buy a whole new console.
This basically puts the nail in the coffin.
im with you on this one, but some people dont get it. Sales and support have nothing to do with what a system could. Sony released a their version of the wiimote without the need of having to release a new console and as many people pointed out, the Move is just a black wiimote. MS did something similar and I dont know why he was even comparing a damn add-on to a new console.
