Here's a theory though: maybe the $200m is an investment in TSMCs 20nm process. As a small part of the deal they'll work on a 20nm mining chip for Avalon and use it as a sort of test chip, boosting the profit on the R&D. Then, maybe Lewis gets a cut of the revenue from said 20nm process. Most of the money wouldn't be for bitcoin chips, it would just be for fab R&D, and most of the profits would just come from regular fab work, not bitcoin miners.
Or, maybe Joe Lewis only bought into a small part of $200m that TSMC is planning to spend on R&D, and the larger number go reported.
I think though the $200m figure is way off, although it seems likely there was some kind of deal if this is all being reported. The WSJ wouldn't just go off internet rumors - they would have had to have been actively conned by someone for this to run if it's completely false.

its a bit like watching goldfish swim round and round in a bowl.
That doesn't really mean all that much, though. It could be like all the "I'm not running for president" type statements. If the story is false it would be a big black eye for the WSJ. I'm sure they're looking into it in more depth right now.
