Right folks, just had a call from Yamaha's UK PR clarifying the situation on the RX-V1900.
They had originally planned to keep the model going until the end of the year, as we were told, but the launch of the replacement model has now been brought forward to mid-October/early November.
The last two shipments of RX-V1900s have already been sold through to dealers, so no more orders are being taken. There is stock available to buy, but it looks as if you'll have to hurry if you want to get one. We don't yet have details of the new model, but I assume it will be around the £1000 mark as before.
However, the RX-V3900, DSP-Z7 and DSP-Z11 will continue for the foreseeable future as we previously said.
