The annoying thing is most games either:
1) Are unreleased as you have stated, in which case we don't know
2) Have proper benchmarks available online which can be researched rather than relying on anecdotal evidence (don't forget over the years we've seen plenty of people going "yeah yeah Crysis runs smooth as butter m8 maxxxxed out on my 8800GT", "You guys must suck at configuring ur PC, I've got a A64 4000+ GTA4 runs absolutely fine" etc etc).
3) Have users give subjective assessments of performance using random settings and just 'wandering around' rather than something concrete and repeatable that also assesses minimum framerate in high action scenes (in my experience, if you only get 60fps just mooching about, chances are when the **** hits the fan the framerate will drop well under 40fps).
4) Have a demo so people could test for themselves
