I have a theory about what the upper left arrow means by pointing off and away from the triangle. That arrow represents Canon users that give up and change over to Sony/Nikon/Panasonic/Olympus/etc.:

Sony is the most likely since Sony has less invested in DSLR's. Unfortunately, Sony persists in failing to provide features expected in camera bodies at this price point for the more advanced photographer market sector.
For example, I would purchase a NEX 7 plus the new version of the Metabones EOS to Sony E-mount adapter to provide a digital back for my favorite Canon lenses while retaining their image stabilization and electronic aperture control. The NEX 7 reportedly has good focus peaking (3 selectable levels of focus peaking) for my focusing needs on that body. For a small, quiet, reportedly high IQ camera, Sony's new RX100 might become my new always-with-me camera.
However, Sony's NEX 7 and the RX100 both fail to meet one of my critical needs, autoexposure bracketing. The NEX 7 and the RX100 will autoexposure bracket a maximum of 3 exposures at a maximum of only +/- 0.7EV! Furthermore, this is never stated in the Sony's RX100 manual (which sets a new standard in inadequate documentation); you have to find out this from user reviews.
The NEX (and probably the RX100, but you can't find out from Sony's "manual") has an HDR mode, but then it only saves JPEG's, not RAW. What were they thinking?
I also have a theory why Sony continues to provide such inadequate AEB on some of its top end cameras. Actually the AEB specification was written to provide up to 7 exposures with each step up to 3EV. However, someone mixed up the numbers and a decimal point and it became only 3 exposures each up to 0.7EV steps. This error now perpetuates itself because no one wants to admit it; the loss of face would be too great.
