So I was at work today and a coworker was telling me how you can buy an attachment for the PlayStation 2 that plays PS2 games in High Definition. So I got to thinking - what is the possiblility of Nintendo releasing an attachment for the Wii console itself? let's say between 1-2 years after Nintendo Wii's launch Nintendo releases an attachment to "up the ante" of the Wii. Is that possible? Meaning, the Wii does have 2 USB ports, but is that in any way possible? It would be very interesting to see if it was possible, say they had some "Wii HD Upgrade" Nintendo would release 2 years from now to attach to the Wii for a GPU/CPU/PPU upgrade. Don't get mem wrong, I am not sure if this is at all possible but i was just curious to find out. What does everyone think?
