I 'think' that I found my answer after talking to Sony for 3 hours
Dolus - Thanks for the input! Sony seemed to almost forget the portion on wall mounting in the installation manual. As I type this my husband is installing the KDL55W800B to the wall using a VESA mount. After talking to 1 manager and 3 different service representatives from Sony yesterday - all-in-all, 3 hours of my life that I will never get back - The 55 inch IS - I repeat - IS VESA COMPLIANT. Use the provided "Wall Mount Attachment" - better known to my husband and I as the long screws - and it makes the television flush with the VESA mount. If you wish to wall mount it using the stand you must purchase the 'Wall Mount Bracket' (not supplied and they don't tell you how to order it or what it is for). To Sony's credit: They are sending us the Wall Mount Bracket and everything we need to use the stand to hang the television for free. The only hitch: It will take 2 weeks to get here, thus we went ahead and got a VESA mount so we will no longer have a $1300 paperweight in the corner waiting to be drop kicked by one of our children.
This entire process was extremely frustrating for both my husband and I. From delivery to actually getting it onto the wall took close to two weeks. Everyone that we've talked to, including multiple reps at Sony and Best Buy, said they were trained that both the 50/55 800's series were not VESA compliant and could be mounted on the wall by converting the stand into a mount using brackets of which Sony provided with the television. It was almost like they originally planned on making the 55 like the 50, only saw the backlash they received by requiring an adapter for VESA mounts, corrected the problem by supplying the "Wall Mount Attachments" but forgot to change the screw hole locations on the stand and update their installation manual. I hope that this post helps someone else like us who were super excited to have a highly rated television but punched in the gut by, what should be, a simple installation process.
