We switched most of our banking over to USAA last year (WaMu was pretty good for a bank, but USAA is stellar). We've still got an account at WaMu, though. As recommended, we'll continue to use WaMu's website as usual, and we're not really worried about the security of our well-under-$100,000 deposit. But we were curious about what's going to happen when at our local branches. Consumerist found a banking insider to provide a one-year timeline of the assimilation process. Short version of the prediction: No big changes for about 6 months, but by the end of the year you'll be writing Chase-logoed checks and saying "good morning" to different faces at your local branch.
