Right, so my curiosity around the Mirror's Edge statue got the better of me. Here are some more photos for those who are interested.

Without being any kind of paint expert, I am inclined to believe that these are not just repainted versions of the statues which are sold at retail. With there being such dark colours on the retail figure, which would have been behind the new white paint, I would have expected this to show through if only a thin layer of paint was applied. Equally, if a thick layer of paint had been applied, this would have been evident by the loss of detailing with the figure. None of these seem to be issues.
It definitely is a white paint job and not white plastic. The Tattoo on Faith's arm is on top of the white paint also, incase you wondered. When packing it away, I did notice a bit of paint had rubbed off the bottom on the one corner of the base and the plastic is like a semi clear plastic instead of black which is used on the standard retail figure.
I expect that these figures could have possibly been pre-production figures which were left over and then just painted white and banged inside a regular CE box. The outer box is no different to the regular CE and the shipping container is the same too. I hope this may help people and satisfy the curiosity of some.
