WSJ -- It Might Actually Happen: Genzyme and Sanofi-Aventis have agreed in principle to a deal and plan to nail down the details in the next week, though there is still no guarantee of a final agreement, the WSJ reports, citing people familiar with the situation. Genzyme has previously rejected Sanofi’s $69-per-share offer as too low and instead wanted something more like $80 to sell, but recently “the two sides have made significant progress in bridging the value gap,” the paper says.
