So they will just lubricate it or replace something ? I guess we'll see some oilsplatted sensor if lube is all they will do to fix this 
That's what i'm afraid of.. Every time i send my camera for repair in Finland they do fix the problem but they don't take good care of the camera.
I replaced the bottom lcd screen (plastic) on my old 1D Mark IV and they replaced the glass with a new one but the new glass was slanted and it had a ton of dust inside like they swapped the glass at a construction site.
In short, i don't like canon service in Finland and will send a million complaints to canon if they mess up my new 1D X at "repair/service"
Also i have a question.. canon said this:
"Potentially affected cameras will be inspected and repaired free of charge. If you own one of the potentially affected cameras please contact our Customer Support Center"
Does it mean that my newly bought 1D X is potentially affected because it belongs to the group of "insufficient lubrication" OR does it mean that i can only get it repaired after the symptoms appear? (a.k.a after there is already wear and damage to the camera)
