Welcome to the forums,
It would be nice if they would continue to support PI, however I really doubt that will happen. They have invested so much into PSPP, along with having CorelDraw Graphics Suite, it simply is not profitable for them to keep this program. They dropped the best video editor Ulead had, MediaStudio Pro, and Corel had nothing along this lines until they swallowed up Ulead. I guess the money comes from selling a lot of cheap products, over a lessor amount of more expensive, yet better quality.
So long as you have an operating system that PI will run on, there's no reason to throw it out.
