Florence: Wikipedia will have stable versions, wiki-to-print, and collaborative video editing.
F.D.: First of all, improvements to the software. This is something that's been under discussion for two and a half years: stable versions. The idea is to be able to identify which versions have been validated, and to enable users to see both the current version and the last version that was accepted as being more or less correct.
The second innovation, which I hope will become available in spring, is to give people the chance to put together a small personalised pdf file or paper version containing a selection of articles. Suppose, for example, that I want to know all about the Davos forum. I put things in a basket, just as on Amazon: the article on Davos, articles about the various personalities attending, global warming or the economic crisis. I compile my own little book which I can buy and have sent to me. That is Wiki to Print.
The third innovation, probably in autumn 2008 will be the possibility of adding videos to Wikipedia and editing them collaboratively, like a wiki text. That should be really, really good!
Wiki-to-print has been around for awhile as pediapress, but there were all sorts of problems with the implementation. Now that I check their site, it looks like they've "entered a long term partnership with the Wikimedia Foundation". Sweet. Here's the press release from a month ago; it looks like this slipped completely under the radar.
