Maybe I can be the first to speak to the actual Wyden–Heinrich letter [1].

I hope I don't sound like a spook when I say: there's been no splash because there's no (public) substance. Having read the 70-page PCLOB report [2], I can summarize it as:

- the CIA has EO 12333 authority to perform bulk surveillance

- they use it to [redacted], including financial transactions

- they have a [redacted] internal process to review its use which potentially has some gaps and vagueness

Sens. Wyden and Heinrich probably have more shocking secret info too. But yeah, I'd expect people to not react to these vague disclosures the same way they did 2013's detailed leaks.
