SuperG you are right up to a point. That point being that it seems insane for a company to expect us to invest in a product that has hardly changed and forces most of us to duplicate plugins. I can understand no wanting to rewrite so much code, but Sony is a large enough company to allocate the resources. They missed a golden opportunity to make this change when they released the Mac version. This surely required a massive look and rewrite of original code. A little extra to upgrade both versions to 64-bit at that time would have made sense. Instead they are still content to keep repackaging Sonic Foundry's 15 year plus old dx plugins.
You're quite right, though, the point being that a lot of us have 64-bit plug-ins now. As far as the 64-bit rewrite, I'd say they've already amortized a large portion of it in with their Vegas product - you can easily tell that Vegas, Acid, and Sound Forge once had a common code-base just by looking at them.
My current beef with Sony is mostly their inclusion of certain dialogs and controls that were obviously built on .NET code vs their standard native-based GUI widgets. (Not to be confused with their *excellent* .NET scripting capability - something I really wish cake had!)
Those controls are not
nearly as crisp, responsive, or pleasant to look at. In the early days of this issue, some of those changed controls lost functionality and I had to file reports. They stand out like a sore thumb too, because the .Net based control have a completely different look and behavior - the flat look popularized by tablets. Mix and match is not good....
Now, Sony's making Mac apps, which is all well and good, but, heck, you would hope they they'd keep their eyes focused on the their flagship.
