SD1 Merrill to sd Quattro - What have we lost?

Why are the reactions almost identical after every major launch? I remember the moment, when Sigma released SD14:

• per pixel-detail has gone!
• higher noise even at ISO100!
• where are the deep shades of blue? skies look ugly now!
• where's the dynamic range?

Again, when Sigma released SD1 aka Merrill:

• where is the per-pixel detail of SD14?
• where are the exquisite colors of SD14? skies look ugly now!
• foliage rendition is awfull! the strong point of Foveon has gone
• shadows are desaturated!
• it lacks the right Foveon look!
• high noise even at base ISO!
• where's the dynamic range of SD14?

Well, now with the Quattro I can almost copy / paste the previous list:

• where is the per-pixel detail of Merrill?
• where are the exquisite colors of Merrill? skies look ugly now!
• foliage rendition is awfull! the strong point of Merrill has gone
• shadows are desaturated!
• it lacks the right Foveon look!
• high noise even at base ISO!
• where's the dynamic range Merrill?

There are two possibilities - Sigma always fixed these issues between those generations - or - photographers learned how to use new models properly. I can't imagine any other explanation, why is Merrill praised for the same properties, which were criticised at the time of its launch.
