which is doable now already, just search youtube for Wii Head Tracking.
Keep the case design similarity "Apple" like, nobody believed me, but product design is actually very important in sales & marketing, even for a game console!
All the hardware improvement will be typical old school Nintendo, like what Apple is doing now... buy massive to lower cost, getting the best technology at the certain price point.
"Euphemism" is the wrong word, what you meant is "idiom".
I liked Ouendan a lot more than EBA... overall, I like Japanese voice acting more than English ones even though I don't understand what they're saying. They just have better, more natural voices compare to our English ones which sound nothing like how we talk in real life. I think localization should be kept to a minimum. So what if we don't understand Japan's culture, we are humans and we're capable of learning. The differences are what make life so much more fun.
The upgrade to FZ50 is what I'm waiting for too... hoping for a drop back to 6~8 MP with good sensitivity (less noise). Everything else about FZ50 is already perfect! Well... I wouldn't mind having a faster or wider lens. (28mm? f2.8 throughout zoom range?)
