>implying Smash 4 will be out before 2014 at the earliest
>implying NSMB Wii won't be a launch title
Come on son.
Firstly, I went out of my way to list NSMB Wii U as a potential launch title. So I guess you just misread that. No harm done.
Secondly, don't believe Sakurai's Smash rumour crushers.
Well they started hiring last summer no? The first task was to have a programming team port over Brawl to the Wii U, and then go from there. I'm sure this is where they are in production.
I agree with you, and am arguing just that. There is no way Kid Icarus will prevent Smash from launching as soon as it possibly can.
It was not just an upscaled NSMB Wii. Those were four new levels. That is definitely a Wii U project. Obviously it will look better by the time we next see it, but I would expect NSMB and the Wii Sports / Wii Play to keep the same motif we previously witnessed. They are not going to feature mindblowing graphics. That will be reserved for other titles like Pikmin, Galaxy, Zelda, etc.
It was an upscaled NSMB Wii in that it brought absolutely nothing new to the table (levels, Mii integration, and other minor tweaks aside). But that was expected, since Nintendo themselves stated quite clearly that it was nothing more than a tech demo (the laziest of them all), and not representative of any title in development. The main reason they had it there was to attract media attention and show NSMB (as well as other popular Wii games) in the announcement video.
It's likely, however, that:
1. NSMB will be a launch title;
2. They'll tweak and re-use the NSMB Wii engine.
