I think I disagree with almost every point you made :P
- The two missing dungeons were a non-factor (I didn't even know about this until just right now). The game wasn't buggy, and it felt complete. It was as good as it was going to get.
- Sure, a bunch of console-vendors bit the dust with CD-ROM, but nobody blamed CD-ROMs. They failed because of price, or because of lack of recognition, lack of games, or whatever, but not because of CD-ROMs. That's not me talking with the benefit of hindsight. I remember being in that era. There was a consensus that optical media in general, and CD-ROMs specifically, were the future. They were cheaper, and could hold huge amounts of data and FMV clips (FMV was big!). Nintendo had their reasons to go with cartridges, but they weren't good reasons for customers and publishers.
>Likewise, the Wii was slated when people saw the Gamecube-level specs with no HD, but then it was successful beyond anyone's wildest expectations.
Yeah, it was a success and let Nintendo survive that console generation, but that success didn't do anything for the Wii U and the Wii kinda lost steam near the end (didn't most 3rd party publishers abandon it mid-way through it's life?). They got really really lucky with the Wii.
