I'm keeping my eyes peeled for any information about a Japanese Famicom version being released here. Right now, it's only 9 am. At the earliest, NCL has new information out for the day starting at 10 am.
Regardless of this thing coming to Japan or not, this is really cool! I'm gonna work out a way to get one. About no internet connectivity - with this product I don't think it really matters. It seems like the purpose of this thing is to be simple and to tap into nostalgia. It's vintage-sploitation at its finest! If Nintedno wants to give us more games, I'm sure they'll throw another system like this together and sell it. They gotta do something with all of those refurbished Wiis and unsold Wii Minis! :-p
