Should I jump from XP to Windows 8?

I’m a web designer/creative/business user ready buy a new computer to replace my current XP PC. Since the Windows 8 release is approaching, I am thinking about jumping straight to 8. Most of the software I run (MS Office, Adobe Creative Suite, Quickbooks, etc.) is the latest version. So I would use my current software on the new computer. What problems could I run into if I skip Win 7 and go right to 8?
