The only difference is that the 507 is coming to the US. So BMW does know how to do special editions. I blame the US govt.
BMW M3 - Mercedes C AMG
BMW M3 Competition - Mercedes C AMG Performance
BMW M3 Edition (paint) - Mercedes C AMG 507
BMW M3 GTS/CRT - Mercedes C AMG Black Series
All Mercs went to the us, BMW sent ony "special" paints that you can order through Individual. M3 has had no technical improvement unlike C AMG and IS-F.
