I think these are mandatory at this point, so here are mine. Forgive me.
More consolidation in the data integration world. Most of the data integration companies have been around for a long time, and they are either huge or small. In 2010, the larger players will surely buy up the smaller players, before the prices get too outrageous as the market recovers. The good news is that most of the smaller players have a good customer base and tasty technology.
Cloud computing drives much of the growth of data integration. While we've not see this as of yet, the continued interest in cloud computing will certainly drive a lot of data integration in 2010. The fact of the matter is that enterprises don't think about data integration until they have already moved to the cloud. That's like building a house without a driveway.
Data integration standards around vertical spaces continue to emerge. Nothing new here, but in 2010 there will be more of a focus on data integration within vertical spaces, including health, finance, and government. Metadata and security standards will lead the way.
Security vulnerabilities will be exploited. Needs to be some bad news as well, and I believe in 2010 we'll have a few instances where bad people exploit some vulnerability within data integration technology. Thus, we'll see some data leaking out, but not much worse than the stolen laptops and data theft via a USB drives we've seen in the past.
