Good point on build-up plan. One of the reasons I don't (personally) like the idea of racing more than one marathon a year is the fear of being a bit mentally stale, cracking on with a new schedule when you've just recovered from the last one. With a good base, not to mention a handful of marathons already in the legs, I'd be tempted to stay short/sharp for a while then have a couple of months' max for marathon specific training from early/mid July onwards.
re: Berlin course, I don't know about the tarmac but apart from it being flat, the roads are generally nice and smooth, and you also get lots of nice looong, wide, straight roads. Makes it very easy to coast along with metronomic splits.
