That's going to be a plot point for the new avengers for the forseeable future.

Pepper is still around, I think she's supposed to assist Tony and Maria while they are on the lamb. I do wonder if she'll oversee Tony's company while he's away. Rhodes has done that before (but he's gone all cyborg now. WTF?)

has anyone, at this moment, tried to seize Tony's accounts, etc?

Not yet (as far as I know).
