I know this is the news section, but I think that the fact that we have not seen the One Max at IFA is news. It seemed to be on every tech site's "What to Expect at IFA2013" list. My personal speculation is that it won't be ready to release in the next few months, so they are holding off on the announcement. There's also the possibility that they are planning a separate event after IFA and probably after the Apple event so it won't be sharing the spot light. Let your ideas roll as to why it didn't make an appearance!
