More from Omaha: Andrew Ross Sorkin asks if Dodd-Frank banking rules will affect the profitability of Berkshire Hathaway's (BRK.B) investments. Buffett says investments in US Bancorp (USB), M&T Bank (MTB), and similar holdings are not likely to be disproportionately affected, although returns on tangible equity at some holdings will be lower going forward. Buffett also opines on speculation, saying subsequent bubbles will not likely be the fault of the financial sector. Munger: "I do not see why massive derivative books should be mixed up with insured deposits ... [I don't like] bankers acting like investment bankers." (NY Times, WSJ)
