Presumed future risk

Professional-looking slider controls can easily be integrated in Matlab GUI.

We can set semi- and fully-transparent colors in HG2 for multiple graphic objects, but making these settings stick is non-trivial.

Matlab's new HG2 graphics engine includes many new undocumented events that could be used in various ways.

the behavior of Matlab's copyobj function changed in R2014b (HG2), and callbacks are no longer copied.

Matlab's dual internal serialization/deserialization functions can be used to create duplicates of any object.

Matlab includes a variety of undocumented internal controls that can be used for an auto-completion component.

Matlab's view function returns an undocumented output transformation matrix.

MCOS property initialization has a documented but unexpected behavior that could cause many bugs in user code.

Titles to plot legends are easy to achieve in HG1 (R2014a or earlier), but much more difficult in HG2 (R2014b or newer).

Infiniband networking can significantly improve PCT performance in Matlab parallelization and distributed computing.
