You're gonna have to wait a long time for that laugh. The space you pointed out is the battery's space. where did you get "DOUBLE the sales" from? Non-educated guess or just dumb speculation? The previous revision had FW400 not 800 which requires much more power. And your main point of argument is that they designed it ONCE but that's not true. They must have thought about the FW port in the first prototype but found some problems with it, then redesigned it to exclude the FW port.
