For projects such as the CS 737 and 727 that customers paid for but never saw finished, it's nice to see there are resources available to ease the frustration and disappointment. Through community efforts and sites such as Simbrief, these unfinished projects can be brought to life and enjoyed, even by those (such as myself) seeking a higher level of detail and authenticity. I'm a huge fan of Simbrief and glad they're supporting the classics. I've never seen a RW commercial airline flight plan but I can't imagine they contain too much more than what Simbrief incorporates.
So utilize the resources available and enjoy these great classics.  No reason not to. As time moves along and in spite of what CS says (we're working on it), realistically, I'm not sure there will be an update  for the 732. If that's the case, it won't stop me from enjoying what I do have.

Cheers,
