Did they actually decrypted the files after getting money from victims?

It would be interesting, if some white-hat security researcher, pays the $300 money and gets the solution (reverse engineering) . Make its available for free to everyone :)

As much as parts of the worm do look kind of amateur-ish, it's probably still a stretch to assume that they used the same encryption key for every infection.

It depends on the implementation. Even so, it's always easier for the authors to patch the malware than it is for researchers to reverse it.
