Yes, its true some of the applications are indeed processed in CIC-M, you guys can check out in the September 2014 thread. Atleast one each from London, Sydney and Manila have been processed in CIC-M.
Also the fact that in the new IMM0008 form they have removed the question as to where you wish to process your file indicates that they might increase the number of applications to be processed in CIC-M.
Also as they are processing the files at CIC-M instead of sending to local visa offices the SA time's have been increasing. But at the same time it is good for people who's files are clearing up rather quickly.
