It looks like there are no wired controllers for the PS4, so before buying a PS4 I'd like to know exactly how wireless controllers are charged, as I tend to play for hours at a time. I take it I need to buy a separate recharging station (there is an official one, that looks to be the best option) but how long does the controller take to charge and can I just connect the controller to the charger and play at the same time, to save having to just charge, when I could be playing because if not I'll need to buy another controller, so that I can have one always recharging, while I'm using the other?
