Should Nintendo Release a Stand-Alone Virtual Console?

Sven Wohl writes: "While most people are interested in what the NX actually turns out to be, there's another topic I've been thinking about a lot recently. Would it make sense for Nintendo to release a stand-alone Virtual Console? Ever since the Wii came out, Nintendo has started to capitalize even more on its own past and released classic games as download titles for their current platforms. But how popular could such a console be?"
