According to dxomark.com tests, the 2008 Nikon D90 and 2009 Pentax K-x provide very similar quality as the 2005 Canon 5D, so it's not impossible that even less than 5 years will be needed.
Even more impressive - the FourThirds sensor of the 2009 Panasonic GH1 is ranked as competitive with the FF sensor of the 2002 Canon EOS 1Ds and the medium-format sensor of the 2008 Mamiya ZD back (though in practice, the Panny is only competitive with the latter when it comes to DR, or when one increases the ISO).

Well, that actually makes me really wonder about the validity of these tests, or what they really mean.
IMO, you can't compare 4/3, APS-C or FF directly, just like you can't FF, MF and LF, even if they share, to a degree, the same lenses. AFAIAC, it is at best a technical sensor comparison, which takes actual picture taking completely out of the equation.
Kind regards, Wim
