This was actually pre-scheduled for PULSE into discontinued after Stream was announced and when the 20% Multiroom offer expired on the 15th. However, we do have some stock remaining so for now are keeping it active. However, this is the final remaining stock which is finite, so when its gone it will be fully moved to discontinued like Mk3 is (of which there is zero stock and is totally unavailable).
The PULSE series remains a good option as an endpoint especially, and in particular the PULSEmini at its price point, but yes in essence it will not be renewed or continued as Stream series can indeed fill this role thanks to its modular design.
