From the Nostradamus dept.:
...When budgets are tight, the best option is to make use of the technologies you already have and the ones you can get for free. For today's business applications, that means the Web, which will continue its rise as the dominant development platform.

While the Web itself won't lose any popularity, however, expect a little less emphasis on the "Web 2.0" moniker in 2009. For starters, it hardly means anything anymore -- if it ever did. But AJAX and related technologies still haven't proven their value for a lot of enterprise applications, beyond adding UI flash. What Web 2.0 capabilities do make their way into business applications will be the result of open source toolkits such as Dojo, while proprietary products are likely to fall by the wayside -- and that means the marketing hype will cool down a little, too.

Note: Also, Java goes more open, Silverlight still sucks.
