I guess it's slowly time to move on, but many MANY people still use it. It seems that the new Frostbite 2.0 engine will be DirectX 10 and 11 exclusive, meaning no DX9 or Windows XP support.
A DICE developer Johan Andersson has tweeted: 'Frostbite 2 is primarily developed for DX11. XP & DX9 is _not_ supported, 64-bit OS is recommended. Lots of time to upgrade if you havent!' Oh well. Windows XP is almost ten years old now, expect this more and more.
