I have a V+ STB it also is a Sci/At 8300!!
Although it doesn't have any other badges on the face plate other than TVDrive.
I have seen the new Virgin branded ones that look exactly the same except instead of Graphite they're Black and branded Virgin
I'm not sure why the specs are that important it's gonna have SCART and seeing as it's capable of HD there's gonna be HDMi ports also.
Check out this link to quench your thirst for specs:
