Judging from dpreview.com studio shots it seems that the amount of details the E-PL1 12MP sensor can resolve is already very close to the 18MP EOS-7D sensor, so if the above samples are anything to go by, then the E-5 should provide practically the same effective resolution for everything but shots resolution diagrams (where the Canon may still have an advantage).
