The "winterlude" is a sort of break over winter that happens to coincide with trade shows. I started a cloudscape in 2009

Mainly it includes Online Information, BETT and Learning Technologies

This year the Winterlude will also include Cross Media Live although this will not happen as a show till September 2012. It is proposed by the organisers of IPEX, a major print show. My guess is that cross media is sooner than some may think.

Also in 2012 there will be drupa with an innovation parc

Some of the technology could be at the XML part of Online Information.

My take on XML is not that techy, i see it as a way to cope with text. So expect more simple guesses and then actual reporting from the show floor.
