Just days after renewing his public criticism of Warren Buffett's current investment strategy and situation, the well-known short seller Doug Kass is out with a very bearish outlook for Berkshire Hathaway shares.

And this time he's not just making a short-term prediction as he did last year when he bet against Berkshire's stock for several months and then covered that bet at a profit.

Today on TheStreet.com, Kass asks, "Is This the End of Warren Buffett?"

His post includes words like "tentative" and "seems," so it is not a definitive obituary. But Kass does answer his headline's question with a strong 'yes.'
