That Precision 5520 looks pretty tasty, will be a nice upgrade from current M4700, which, while solid and performant, is a bit of a tank and power hungry to boot (180W power adapter rarely works on planes; combine that with the 2 hour max battery life...). Shed some weight (4lbs vs 7lbs), high res screen, 32GB, 2 X SSD, and get a probably modest performance boost for cpu intensive tasks (like compiling Scala projects) -- think I'll pull the trigger when it launches.
