At least one of my cousins in Japan is planning on picking this up at launch, and I'll be pre-ordering this soon too. I might buy the basic Wifi model, 4GB memory card, Gravity Rush, and Disgaea 3 if it makes it to the US launch.
Not sure, but I haven't seen anyone online complain about the heat yet.
If the Japanese launch is any indication, most likely all of them will be available digitally. The exact discount on the digital copies in the US is still unconfirmed, although there are rumors that digital titles could be as much as 40% cheaper.
