OM-D EM-5 - Digital Leveller / Architecture
While it's theoretically possible to do some tilt-shift with this kind of image stabilization, the lack of mention of it probably means this ability isn't designed into the camera. It's also possible that the image stabilization mechanism would need a lot more physical "throw" to provide much tilt-shift capability.
The digital leveler is probably very similar to what's been offered in the E-30, E-P3, and other Olympus cameras - simply a visual readout of the camera's orientation sensor. So you can manually tilt up/down or left/right until the indicators are in the center (and the camera is level). In the case of my E-30, at least, it doesn't auto-level the images in post-processing.
