For the price they´re asking..... they could do just three simple things that would make pratically everyone satisfied:
1 - Voice chat on the console. A simple app working on the background would do.
2 - Offer SNES, N64 and GBA games, similar to what they did with the NES games
3 - Offer local back up for cloud save data on the Sd Card.
As a side note, I tried the voice chat using the smartphone app and it works ok but it does still feel a little cluncky, in my opinion.
