Legacy.

The Switch has just had its first E3 but we still don't know exactly how the Virtual Console is going to work on the system. 

Nintendo has previously spoken about linking some kind of classic game service to the forthcoming paid subscription system, even going as far as to state that subscribers will get a new game each month. However, the company clearly doesn't have a definitive picture on this yet, as it recently went back on that idea.

While Nintendo has already stated that its subscription service isn't a replacement for the Virtual Console, it's becoming clear that the firm wants to get one right before officially confirming the other. 

Speaking to IGN at E3 2017, Nintendo of America boss Reggie Fils-Aime noted that Nintendo is aware of the "appetite" for retro games on the system, but the issue currently is finding the best way to approach it:

We know that our fans, our players, want access to all of our digital content, we know that. What we're working through is, 'okay, what's going to be the best way to make that happen, to make that available?' Certainly, we recognize there's an appetite for all of our great legacy content.

Excitingly, Reggie uses the term "all", which - if you were feeling particularly optimistic - could hint at a large selection of Virtual Console games from day one, and not the rather painful drip-feed of games that we've seen on the Wii, Wii U and 3DS.
