There's nothing new on either of them. I'm allergic to Yahoo! so I don't know what you might be seeing over there. It's not likely that anything would appear there first.
I don't subscribe to Edgar, but I suppose that's what they compile and/or copy from OTC. Or maybe it's the other way around. I assume that's what is posted at Yahoo and said to be from EDGAR Online.
EDGAR® Online is the premier provider of data derived from filings and other disclosure documents. EDGAR Online creates and distributes company data and public filings for equities, mutual funds and other publicly traded assets, delivering products through online subscriptions and data licenses.
It could be Yahoo has an agreement with EDGAR Online and post the info. Since it's somewhat "outdated", there is really no competition for subscriptions.
