Abridged
Think about this if TH truly has parts purchased and sitting somewhere (Assuming the next gen chip will work with them). They might be thinking about sitting on parts ... come out as new bushiness superhash 2.0 (or something) and attempt again with just chip costs, making massive profits.
From how he listed his house for sale in late July, it doesnt seem like his intent is to stick around for long.
Banks probably locked down his account (might need to check if this is at all true-- Terrahash isnt good at honest statements) because he was cashing out too much bitcoins into his bank-- IMHO missed details on transactions beyond 10K per money laundering laws
Either that he was already under legal troubles from someone smart and fast enough to execute an asset freeze
