The defining deals of the week, Kraft’s now officially hostile bid for Cadbury and a deal to sell a majority stake in NBC Universal to Comcast, hinge on decisions of Europe Inc, so they could well drag on many more weeks.

This morning, Kraft formally bid for Cadbury with the same offer mooted two months ago, before today’s put-up-or-shut-up deadline. Cadbury has already said no to these terms, and can be expected to do so again. But the sinking expectations that Kraft might pay more, and the lack of any other buyers coming forward, don’t help to make the case for a successful hold out by Cadbury executives.

Over the weekend we learned that GE and Comcast agreed on a valuation of around $30 billion for a joint venture between NBC Universal and Comcast, ironing out what has been a key obstacle in talks so far. But French media conglomerate Vivendi, which owns 20 percent of NBC Universal, has not yet agreed to a deal, a source said.

So far as NBC is concerned, Vivendi is so far tres mum. Every year between mid-November and mid-December, Vivendi has to decide whether to exercise its option to sell its NBC Universal stake. Vivendi is believed to be eager to dispose of it, but nobody knows what they want for it.
