I am currently using Topaz Photo AI v.2.2.2 and am satisifed with it. I also have the Topaz Sharpen AI app, the Topaz Denoise app, and the Topaz Gigapixel app. Apparently there is a new version of Topaz AI now. From the Topaz website it appears that it would cost me $199 to update to that version. Has anyone updated to the latest Topaz AI version from v2.2.2. Is it worth it? If I don't update does anyone know how long i will be able to use v2.2.2? Thanks in advance.
