Ouch!! --- Thats gotta hurt :(

It's different depending on the company. Yes Sony, Samsung, Panasonic have big overdrafts and are unlikely to just die. Samsung have been a winner in consumer electronics (at the expense of Sony and Panasonic it has to be said), but have had very little traction in the digital camera market (NX has been a bit of a flop I think sales wise)

I'd wager Samsung might be leaving at some point

Other smaller players such as Ricoh/Pentax are probably under more pressure

As for Fuji I think they have unlike Kodak done "different stuff" and probably enough to ensure their survival, mistakes yes but decent stabs no question.

I'm not sure Minolta couldn't have made a go of it, they were no.3 so it was more a Konica driven move and Sony's cheque book opened up nicely for them.
