Greetings!
Well I tried to post these to the "Arkham City Limits" Facebook page, and they were taken down with no warning - probably for not being the 'official' figures. Which I think is a bit churlish, but anyway I thought others would find this useful.
I am building up some models for the game, I am mainly focusing on the 'Dark Knight' movie side of things. Got a KM Batman and Bane so far, and am now building up some crews for them.
While the official henchmen models are nice, I don't have any yet, but did have some Airfix 1/48 Modern British which looked to be the right size. Good way to test out the game and see if I like it, before I commit too much to their decidedly expensive models. Still need a bit of greenstuff and gap filling.

Yes they are covered in gear and very 'military', but I think they will look like Police with the right paintjob. There have been recent articles about the militarisation of Police forces around the world, and I expect the GCPD would be right at the forefront of this, given the diabolical villains they have to deal with! Grey bits are Wargames Factory survivor bits, an excellent source of bits and pieces.
And a size comparison pic with a KM Batman;

Note that these are the Airfix 'Vehicle Crew' models, and not the Infantry Patrol - there is a significant size difference between the two (despite both being listed as 1/48), with the Infantry Patrol being much smaller and more in line with 28mm models.
I suspect with a different paintjob and more 'casual' heads, I could make some Bane mercs as well!
Hope to get some paint on these soon.
Cheers
The Baron
