I do agree that shares usually fall, but if include the reveal in December, Nintendo's share prices have almost fallen by a third. That's a pretty big drop for a new console (not as bad as when the Wii U launched, though).
I'm interested to see what the bundle prices end up being. Walmart say their bundles could start from $400, so could be pretty expensive. Using 32GB memory cards again won't help, either (but it sounds like it should be easier to expand memory). Makes me wonder if they have so many leftover 32GB cards, that they have to include them with the Switch. XD
