The article Which license edition is the best for me? explains differences between Bundled and Ongoing releases and why they exist. In a Nutshell, in comparison with Ongoing versions, Bundle versions will most likely:

• Be older.
• Miss 5 or more features and improvements.
• Take longer to be available for newer Maya versions.
• Possibly have more bugs.

But... how long exactly will it take for the next Bundled release and what are the missing features/improvements currently? This page will be constantly updated with the latest information about that.
