I do think things will mature, and we'll get data in the cloud. Even financial data, but it will not be the mainstream, IMHO. Just like the web, we'll get private clouds for secure stuff.

Wells Fargo manages their own data centers because it's important they control the servers; they wouldn't put it in a colo with other companies. Mint hosted their stuff as a startup because it was cheaper. We'll see that with cloud databases, just as we have with cloud web servers.

They have a time and place to be used, and fitting everything up there doesn't make sense.
