Why No XLR Input on 6600?

When I got my 6500 I thought, wow!, finally a rig with an XLR mic input. Why has Flex removed that option from the 6600? The back panel is much larger than the back panel on the 6500/6700, so why not use the same type of combination XLR/1/4" balanced mic connector?

Was it a matter of cost or is there some technical reason?

When this was initially discussed, it was in fact a cost issue. Specifically cost of manufacture and assembly.  The radios were initially slated to have only the 1/8" connectors, but eventually they decided to also add the 1/4" TRS connector. 

The 1/4" TRS connector is electrically the same as the XLR for balanced audio. The 1/8" is pseudo balanced. Field testing has shown it to work very well. One user reported that pseudo balanced was better than balanced, but I don't think that was done with instruments, just anecdotal reports.
