Has Sidi's sizing changed?

Older size conversion charts have Sidi's Euro size 43 = UK size 8 = US size 9, but I have seen the new Ergo 2s for sale with the claim that 43 = UK 9, and on a US website as US size 10. Also I recently tried on a pair of 43s and I'm sure they are bigger than the old 43.5s I have and maybe about the same as the old 44?
