At least Sony has figured it out. They had AF-C on the RX1 in an early production model and then removed the mode for the final model that shipped to consumers.

True. I guess the main point I was trying to make was that no manufacturer currently has a good AF-C solution for mirrorless. This is one area where any DSLR will crush a mirrorless camera.

Well, DSLRs aren't very good in high speed burst mode either (that is where SLT advantage shows up). The typical DSLR will get highest burst rate in release priority mode, which locks focus on first frame. The slower rate will have AF-C through the mirror.

In SLTs (and in NEX with EA2), full time AF-C is maintained even at highest burst rate (10 fps in A55, for example). The limitation, however, is that exposure is set at the first frame and at f/3.5 (however, switching to AF-S allows control over exposure but then... no AF-C). You'd have to settle for 6 fps (in A55) or 8 fps (I think, in A77) for AF-C with exposure control. DSLRs are slower than that.
