FF users (all models) - would you prefer an in-built flash?

I don't have a full frame, but have been watching the leaks on the new camera closely considering upgrading to full frame.

While I can live without an on camera flash, not being about to remotely trigger the off camera flashes wireless without adding some other bits kinda puts me off a bit.

With my A77 I usually use an accessory flash when I need one. But when I get stuff all setup to use it off camera, I use the on camera flash to trigger them. Not being able to do this? well, that's a bigger issue to me that not having the flash. While I'm sure I can do this if I get a larger f58am or similar, that's a lot more money. If they introduce a small $50 controller (similar to what Minolta had for years) that fit in the new (old) hotshoe, that'd be fine.
