Correct on the Hyrule Historia front. Didn't know Sept 20th was the digital release for WWHD, thought it was retail too. Physical HH would have been a deal-sealer for many I bet. Oh well, digital is better than nothing.
Personally I think it's smart -- it'll likely encourage some to take the dive into digital just to play it earlier. It shows Nintendo is serious about have digital content releases.
Which is likely great for us, even if I'll be pining for a physical box. Although, if Nintendo had a proper account management system in place for games (like Steam), I'd probably just be buying digital anyway.
