The bridge between Apple and Samsung is on fire, but given that Apple set fire to it, they probably have an alternative in the pipeline.
Samsung are just adding fuel to the fire; they know Apple's going to drop them anyway, why wouldn't they make as much profit as they're contractually able to?
So it's very likely that Samsung did actually ask for the price hike as soon as they were sued, and Apple has spent the past few months looking for a new supplier.
We already know Apple plans to move to TSMC in the near future, from several reports. Obviously, Samsung will know about this, too. And this is probably just a way for them to squeeze the most money out of Apple by the time that happens.
