    Technical differences.

    Unity

    • Written in C++ as a compiz plugin and uses nux for OpenGL support.
    • Requires hardware acceleration (Compositing). (Hardware requirements)
    • Is shipped as the default environment in 11.04
    • Also does window management via compiz itself.

    Unity 2D

    • Written in C++ with Qt
    • Works on systems without hardware acceleration, like ARM-based platforms, as a result it is incapable of advanced 3D effects.
    • Shipped as the fallback method in 11.10. Is not shipped by default in 11.04, available as a separate package that the user has to install.
    • Needs a seperate window manager (like metacity) to do window management.

  2. Unity-2D is for use with computers that do not support 3D-accelerated graphics, such as some low-end netbooks. Unity-2D looks almost exactly the same as its 3D counterpart, albeit without a bit of the eye-candy.

    As for updates, both should be updated around the same time - although I'll expect Unity-3D will have a bit more effort put into it just due to the fact it is the "mainstream" version of Unity.
