Here is another statement about the voice increase:

Record and mix bigger sessions with more I/O, tracks, and voices

Pro Tools and Pro Tools | Ultimate now support a maximum 64 channels of I/O—up from 32. Pro Tools now supports a maximum 256 mono or stereo audio tracks at all sample rates—up from 128 at 48 kHz. And Pro Tools | Ultimate now supports a maximum 2,048 voices and audio tracks at all sample rates—5x more than previous versions. This means you can track bigger sessions and work with a lot more outboard gear using any Core Audio or ASIO interface. And with more voices, you can handle the largest sessions without constraint.
