Street Fighter 4 System Requirements

I was quite curious about the PC version of Street Fighter 4.Game was a hit on other platforms and we are expecting the same thing on PC.One thing that added an element of curiosity was the requirements for this game on PC.

Before this version we were never required high requirements to play Street Fighter.Anyway Capcom has revealed the minimum specs required to play the game on PC to satisfy our curiosity a bit

CPU:2.0GHz or higher
RAM:1GB or higher
HDD: 10GB of free space or more
Video Card: DirectX 9.0c/Shader3.0 or higher compatible, NVIDIA GeForce6600 series, ATI Radeon(TM) X1600 or higher or higher, VRAM :256MB or higher
Sound: DirectSound compatible, DirectX 9.0c (or higher) compatible

So 6600 will be sufficient to play the game. In OS only Windows Xp is mentioned, which means that it will not run on Vista and Windows 7?I doubt that though and if does not support these operating systems,we will see probably some patches to run on these operating systems. Game is scheduled to release in July om PC.
