Thanks for the information.You should know by now that if AMD marketing is throwing some numbers they are the best case and nowhere close to real world average performance increase. Anyway R7 360 was a partially disabled Bonaire chip with 768 sp clocked at 1050 Mhz boost . 16 ROPs. 128 bit GDDR5 memory at 6500Mhz . Bandwidth 104 GB/s. 1.61 TFLOPS (768 x 2 x 1050 )
https://en.wikipedia.org/wiki/AMD_Radeon_Rx_300_series
With Rx 560 we have a fully enabled Polaris 11 with 1024 sp at 1275 Mhz boost . 16 ROPs. 128 bit memory at GDDR5 7000 Mhz. Bandwidth 112 GB/s. 2.61 TFLOPS (1024 x 2 x 1275 ). We are for sure not going to have 2x perf of R7 360 even when theoretical TFLOPS are only 1.6x . btw performance never scales linearly with TFLOPs especially when the chips have same shader engines, tesselation engines, ROPs and roughly same theoretical memory bandwidth even though Polaris does have color compression which improves actual bandwidth. I would say we will see 30-40% improvement in DX11 games and close to 50% in DX12/Vulkan wrt R7 360.
We have already seen AMD partner Sapphire launch fully enabled Polaris 11 with 1250 Mhz boost for Chinese market. So the Rx 560 is just an official SKU of what was previously a region limited SKU. It will be roughly similar to the GTX 1050 in performance.

The main advantage is the Rx 560 comes with 4GB VRAM as the default SKU while GTX 1050 only has 2GB . I think USD 99-109 is the right price for this GPU. Anything higher and its not worth it as the faster GTX 1050 Ti can be found for USD 130.
Are you sure there is only going to be a 4gb rx560 and not 2gb as well?
Also if its only going to be 40% faster than R7 360 why is amd misleading by advertising as upto 2X faster?
