Sounds like Pinchuk et al know when to play it safe. Not supporting Yushchenko may get them scowled at, but pissing off Yanukovich may get them killed.
It is clear that if they can't steal all of the Ukraine, they intend to carve it up. They want their mafia/oligarch controlled eastern Ukraine to have at least the kind of self-rule that Crimea has, and before it is over they will want independence because they are mostly Russian speaking and don't give a damn about Ukraine -- only lining their pockets with money from Ukraine's resources and kowtowing to Mother Russia.
