Probably not. I don't think the market would be big enough for Apple to add another production line.
sure it would, they only have 1 line now
they could ad another
heck i bet most i-people would buy one of each, just because its an i-product
why would they have to add a line. the cameras are on a separate board in the phone anyway, all it would take is to leave that part out on some of them. This is actually a big deal to have some without cameras, as most government jobs and even military are not supposed to have camera capabilities on there phone in areas they work.
