Curious as I haven't really paid attention but ps4 only launched in the US I believe is that the same for xbone or did they launch in other countries also?
Answering this question proved a little more complicated than expected.
PS4 launched in Canada and the United States and is launching this Friday in Australia, Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy, Luxembourg, Netherlands, New Zealand, Norway, Poland, Portugal, Russia, Spain, Sweden, Switzerland and the United Kingdom as well as Argentina, Brazil, Chile, Colombia, Costa Rica, El Salvador, Guatemala, Mexico, Panama and Peru. Add several asian countries in December (this list proved too hard to find, but it includes Hong Kong, Malaysia, Singapore, South Korea and Taiwan) and finally Japan in February.
XB1 launched in Australia, Austria, Brazil, Canada, France, Germany, Ireland, Italy, Mexico, Spain, United Kingdom, United States and New Zealand. They expect to launch 'as soon as possible in 2014' in Belgium, Denmark, Finland, Netherlands, Norway, Russia, Sweden and Switzerland.
Note that these lists are "territories" not countries, which means there are probably additional countries where the consoles are or will be available, but they are part of a greater "territory".
