Developing Rumour - some/all/part of Reed Business Information's business or titles are up for sale

Rumour came in this morning that Reed Business Information (RBI) is looking to sell something (limited confirmation coming out of the Guardian). Exactly what (titles or the whole) business is not sure. What is strong in the Rumour is that Flight and Travel Weekly are almost certainly going to be put up for sale in the UK. No word on what this means for the other travel publications such as the sterling Travolution. If this is true then two possibilities:

• the seemingly unstoppable travel boom means that the ad sales teams at these titles can't take the orders fast enough ensuring cash flow that would be attractive to buyers; OR
• industry execs have just stopped reading magazines instead getting all the news they need online.

Mark Sweeny in the Guardian thinks it will be the whole business and that it will capture a price tage of GBP1-1.3 billion.

What do you think - is the industry magazine business a dying one or vibrant and worth billions?

UPDATE - PaidContent is also covering the story. Looks like full sale is most likely. Are saying that 30% of revenue is from online.
