Its been mentioned by Ed before, in an interview (i think it was Giant bomb with Jeff) "As you can see the boxes are still floating and not fully connected"

Sorry if its not the EXACT same what he said but he hinted at something very similar.

lol it was a quick cut/copy with Above the Roster how it has always been in MK and under the original MKX select slot formation.
