Should they yes. Will they no. And this isn't just because Nintendo likes "double dipping". It breaks down to three differnt issues legal, technical and imporantly time.
The legal aspect deals with what devices they have to legal rights to publish the game to. I brought this us several times before. But usually in the publishing agreement it lists the exact console that they have the publishing rights to and whether or not the owner of the IP has the right to bring it to other devices.
And since the VC so far has been device specific they cannot just throw it on the next console. This may change with NX and their network becoming more of a service that includes the NX and not a dressing to the console. Though they still need to go through the time consuming and often tedious job of finding who owns the IP, it may have change, getting them to sign a contract that has wording that lists the publishing to the NN (or whatever they are going to call it) instead of a specific device. Also with these types of agreements the time span where they will have to update to terms of the agreement. So they don't have to do it everytime.
The next problem is tecnical and leads to time, who will be doing the emulation for it. Because depending on the title one emulation software rarely fits all, plus the modifications to the code to accept the new controls. Because just because they can use the same controls doesn't mean they process the commands from them in the same way. This is evident in an interview, I forgot the developer, but they wanted a game on the service but Nintendo had moved on to other systems at the time. Which isn't BS because some calls depending on what wanted to end up doing may need different types of emulation procedures done to get the call to work the way the developer originally wanted.
They may have to create a development studio that just does VC software. It's one of the reasons Nintendo gives as to why they haven't been able to get their stuff up it takes time and they would be rather creating something new. And they need to be able to make emmulation for incoming titles. This will not be a small team since depending on how optimized and what type of optimizing was done depends on how much of the code needs to be rewritten.
