Going to reiterate as it seems some folks don't want to believe it.
Look at what they are planning on giving with the paid online service, an updated classic title with more features.
They will be selling those titles as well.
So stop for a second.
There is no artificial delay. There no sinister we need to sell X so hold back Y.
To me, the online plan explicitly shows what direction they are going to go with future classics from them. Updated versions of their games with more features. Whatever they may be.
This won't resemble old VC at all in that, hopefully, the features are meaningful, like online co-op in some games or leaderboards or rewind functions etc. Things people come to expect when replaying old games on good emulators plus more.
That all takes time and effort and money, and if they want to charge everyone for the same games again they need to change the rubric. They have to go in a different direction. It also provides them an out for people who want to just upgrade their Wii/Wiiu VC library or migrate it. Going this route they won't have to give up anything. I firmly believe the update pricing turned a lot of 3rd parties off of Wiiu VC.
I also expect to see more things like USF2 - Switch, or the Mana series collection, and the Neo Geo titles. They aren't interested in making 3rd parties bring their classics from system to system anymore and are encouraging them to go their own path.
Hell they even have Hamster doing the Nintendo arcade games. Which I believe points even more in this direction.
