Robert posted this on the PMDG forum. The 777 (followed shortly by the 737) will have full PANS-OPS compliance. Apparently aircraft from other devs do not, according to him (not sure how accurate that is.) Great news, nevertheless.
Many many developers beat us to using Navigraphs new format, but part of the time lag for us was the implementation of the entire ARINC 424/PANS-OPS with full compliance for all leg types. This is a pretty significant change, and while many developers have been reading the ARINC 424 for some time, they aren't actually doing the full suite of path computations with associated control logic to ensure the airplane complies with the defined path for specific procedural legs.
