Very interesting, specially considering the I2S output. I could easily have missed it but I did not seen an estimated shipping date.
It seems like a Kickstarter campaign.
Probably not released before Q2 2015 if I understood correctly.
I have been reading ‘everything’ about it for the last couple of days.
It is still not absolutely clear to me whether it is a closed system or if it contains an uPnP server (I have seen hints about it, but no positive confirmation) which in my case is an absolute must if I am using the internal storage.
It seems to support DLNA and NAS.
It is a bit unclear when the launch to market is planned.
