Um...isn't that transaction still on hold pending the outcome of some lawsuit?
AFAIK there is still no update regarding the lawsuit , but looking at how monsterbyte is working and promoting nessie these days then I guess you can consider it official since it doesn't make since to work on something that may not be yours in the coming months
I'm not 100% sure, but I think the acquisition was confirmed. Perhaps, but this is just my conjecture, it is those liabilities (financial debt) that was not absorbed, only the assets. It can be quite typical in a business sense for the acquirer not to take on any old liabilities, not only for legal purposes but business ones.
Nessie-MoneyPot-BitcoinRush. That's no longer pending. That's all Monster Byte now, as explained by this blog post. And yesterday's blog post here seems to confirm that along these lines. Actually, just reading those posts there will give a clearer picture.
