"It's the ultimate trojan horse method to lure a big part of the market back. Once they're back for the retro gaming, they may pick up Pikmin 3 and realize it's not what they thought it was, and their faith in Nintendo reborn, they go out like prophets and spread the word.. "
That might work. I'm iffy about it though since we've seen a trend where original Nintendo games aren't selling nearly as well as Nintendo spinoffs and sequels. By focusing too much on the franchises Nintendo has been training its customers to only pay attention to the sequels.
