I kind of assumed all along. I was crying vaporware the whole time though - I'm surprised they released something. The signs were there in the marketing - they never showed anything other than pretty cg mockups the entire time, the only videos they showed of functionality were clearly fabricated mockups - even < 1 year to release date. The closest they ever came to actually demoing the thing was showing some celebrity using it.

If they actually had anything nearly as impressive as they were claiming they wouldn't acted so obviously shady.
