@lolilol1975, a lot of this was discussed in the Live Developer Q&A this week. Especially around the 52 minute mark. The Bing Maps team is working with companies like Planet.com, and they know what data is scheduled to come out in the future, and at what resolution. Where it makes sense to update, they will. The US has tons of aerial mapping survey aircraft flying grid patterns every day. Getting ultra high-resolution data for the US was probably the easiest of all the places you mentioned. There will be many more areas to come on a 2-3 month rolling basis.
