Just a guess here...
I don't think what we saw last night would have required the Pro Tools programmers balls-to-the-wall effort to implement.
I think Avid wanted to:
- Get an "Avid" branded Pro Tools out there
- Get something at least somewhat earthshaking out there for the AES show
- Get an "exciting" product out there for the holiday shopping season
But I honestly don't think the PT9 that was released last night was Avid's end game for the product. I think it was the most Avid could cram in there before a certain date (AES show) without diverting too many programming resources from what will be the real "biggie", a 64-bit version.
And I think we'll see the 64-bit version before summer...
