The japanese website DC.watch (Click here for the terrible google translation) interviewed the Olympus E-M5 developer team. Sadly the google translation tool makes a bad job and it’s quite frustrating to read the text. From what I understood there is no BIG info. But may you read it and let me know if you found something I missed. P.S.: They said that there is no significant difference between the amount of Silver or Black E-M5 pre orders. At the same time DC.watch posted an E-m5 review too!
Meantime DSRLcheck keeps posting new mirrorless camera comparisons:
