My PS3 would do nothing but complain and claim I hated Sony because I only have two PS3 controllers, one of which doesn't have rumble, while I have 4 360 controllers, and 5 Wiimote/Nunchuks.
My 360 would probably try to put down my PS3 on the basis that I spend more time using it as a Blu-Ray player and Media center. Then it would have a horrible moral dilemma as it tries to refuse to work on my Sony HDTVs, and considers sabotaging them, until it realizes it would be hooked up to a Phillips TV in that event.
I think my Wiis would just end up gloating and trying to start flamewars with the other systems in the house, as there are two of them, I have more Wii games than PS3 or 360 and play my Wii the most. Then complain I hate Nintendo as I still have a DS Phat, but have a Slim PSP.
