shadow and light created by objects...
Reminds me about a flash or something. May be some EX-440-RT.
Probably not a 4x0EX-RT, that would be a pretty significant (global) announcement. However, a while back there was a rumor of a new flash coming for the EOS M system, sitting above the 90EX in the lineup. The light/shadow thing, coupled with an announcement in a prominent Asian market, are consistent with that.
Regardless, it seems like we don't have long to wait.
