At present it's unclear if these cards are exclusively for the OEM market or whether we'll see consumer retail version as well. The R9 380 for instance is pretty much identical to the Tonga-based R9 285, whereas the R9 370 seems to use good old Pitcairn, which was used by the R9 270 and even as far back as the HD 7800 series. The R9 360 is based on Bonaire (R7 260X) and then you also have the R7 350, R7 340, R5 340 and R5 330, all based on last-gen architectures. Most of these cards don't even support FreeSync.
What this means for AMD's desktop lineup is unknown, about the only thing we know for certain is that a new flagship GPU with High Bandwidth Memory (HBM) is coming within about a month or so. But even the naming of that part is still a mystery, everyone assumes it will be R9 390X but AMD has yet to reveal the official name.
This is all just speculation but perhaps they'll skip the 300 consumer series and introduce Fiji under the 400 series and add the mainstream and lower-end parts at a later point? They've done something similar a few years ago with the 8000 series which was exclusively for OEM rebrands.

AMD also officially confirmed the existence of the R9 M375, R7 M360 and R5 M330 laptop GPUS. The R9 M375 has 640 shaders, up to 1015MHz core frequency, up to 4GB DDR3 clocked at 2.2GHz and 128-bit memory bus. Then you have the R7 M360 with 384 shaders, 1015MHz core, up to 4GB DDR3 clocked at 2GHz and 64-bit memory bus. The R5 M330 has similar memory specifications as the R7 M360 but cuts the stream processors to 320 and has a maximum core frequency of 1030MHz.
