Important: as Blender 2.8 is still in development the following may be subject to change.
For Blender 2.8 the Info Editor, the area that previously ran across the very top of the application, has been removed and contents reorganised to emphasise various context sensitive Workspace tabs and application menu options. Missing from the redesigned upper area of Blender 2.8 is the Scene Information section that displayed data relating to objects being edited (Edit Mode) or the contents of a Scene (Object Mode). This data is now shown to the right side of the new Status Bar that runs along the bottom of the application.
Design note: the Info Editor itself was largely an empty area except for the Header which held scene information and various application menus that, although no longer shown within a distinct area, are still available, largely reorganised to make better contextual sense in relation to prioritising Workspace tabs.
Depending on the active Interaction Mode, Edit Mode, Object Mode, Weight Paint etc., the data shown in the Scene Information section may differ; in Edit Mode for example the values displayed relate to the object being edited, i.e. a subdivided Cube, and the number of elements selected, e.g. 8 faces from a total of 384, displayed as Faces 8/384 and so on;
object | vertices | edges | faces | triangles | memory | Blender version
In Object Mode the information displayed relates to the overall Scene, all the available objects within it (meshes, Lamps, Empties etc.);
object | vertices | faces | triangles | scene objects | memory | Blender version
Scene Information changes depending on the active Interaction Mode; in Edit Mode the data shown will related to the number of faces the object might have versus the number selected whereas in Object Mode will display similar information but relating to all objects in a given Scene.
