It’s called “common sense,” Paul.
*Most* people would suspect that were Adobe to license the gFx engine (which they did) and then put it into “future Adobe software” (which they are), that they would in all likelihood not put it into InDesign, Acrobat, Photoshop, Ilustrator or Premiere but into a tool like After Effects or perhaps a standalone app (which I doubt).
But anyone who knows the Securities & Exchange Commission law knows why major publicly-held corporations veil their statements in generalities. They have to or they can be held liable for all kinds of things in this litigious world we live in.
At the rate that Adobe has been acquiring plug-in technologies over the years (which they have), and dumping them into After Effects — the clear market leader in its field — it takes little “mental venturing” to see why most people think we’ll shortly see gFx inside AE.
As a member of the Silhouette development team, you are entitled to your beliefs but being a competitor — and one whose market could be adversely effected by an AE/gFx release — I expect that your argument is less than given from a place of neutrality or balance.
