The way I see this generation, what happened with 3rd parties was a self fulfilling prophecy:
In order for their games to sell well, 3rd party core games need a market. 3rd parties initially didn't believe the Wii will succeed. And some thought it was much weaker than it was, so didn't want to develop for it, or so some said. So at best most gave it half hearted/relatively low budget efforts for a very long time, If anything at all.
As a result they killed a lot of the willingness of the core market that was on the Wii to buy core games on it and a lot more of the potential core market that would have later joined the Wii had the "right" core exclusives been there.
And so they brought on the condition that is the present reason most use to not develop for the WIi - they're afraid it won't sell enough. Unfortunately even those already committed are shaking in their boots, you can see that. I am not sayng they are correct to do that, just that they are.
What does all this have to do with Wii2/Super Wii 3rd party support? Well if Nintendo secure some quality 3rd party core launch (or launch window) exclusives for their new console from a wide variety of developers, its non-Nintendo core market share will grow (while not all, lots of gamers go where their games are), 3rd party core games will sell much better on Wii2 because the market will be there, and so more 3rd party efforts will be made for it moving forward...
To illistrate this with an easy example - get Final Fantasy XV (or XVI) as a Wii2 launch game, and you will see all Japanese core gamers get a Wii2.
