U may be over thinking a bit. This is the 1st 10do console to have a great install base AND a conventional button input in nearly 15 years. Make a system for gamers and put great games on it and they will buy your system it's why I'm perturbed with the announced shift in focus to a more casual audience and the over dependence of budget side scrollers. So much potential for this company.
A console should be able to appeal to both casual and hardcore gamers equally, being lopsided isn't particularly healthy for anyone. And budget sidescrollers? It's just Kirby and Donkey Kong at the moment, where are you getting that nonsense from?
