That is very possible. He could even be a member already.
There is a Leica enthusiasts site in which the singer Seal had been secretly registered and posting for years before he revealed his true identity.
m43s is not mainstream. The masses who don't know a lot about cameras but want "a good camera" will, provided they don't get the horrific $200 superzooms, get a CaNikon DSLR. m43s is for people who do more research.
But with the popularity of the OMD line I see ads in magazines and such. So, assuming he doesn't know a lot about cameras yet has the means to buy whatever he wants, he probably said, "I want a really good camera but some of those are too big." And, the OM-D E-M1 is, without a doubt, the best camera in the world (obviously when considering size, price, etc. The Sony RX100 would also be the best in the world as would the Nikon DF but you know what I mean).
Anyway, I'm glad he has it. That means more people are learning about it and hopefully it'll be here to stay!
