vs Console prices (with inflation for the last 30 years)

There have been some super expensive consoles!

All of the high-priced consoles over this time have essentially been failures. However, many of the cheapies didn't do that well either: N64, Dreamcast, Gamecube, and the Jaguar. This isn't enough to say indefinitely that high-price always fails or that middle-price always wins.

Personally, I think it is going to come down to how much fun the Wii actually is and how much people are willing to pay to game.
