Unless you use one of the camera models only being officially recognised in the new release, probably not.
Picture has a very unfavourable pricing policy. You pay for the latest versions plus 1 year of updates. Fine of course if the latest version has what you need, and/or releases are forthcoming at a steady pace. However in the last two years, progress of PhotoNinja has been very slow and one can easily await a major new version and save the pennies until this appears. If it ever is manifested.
By the way, version 1.3.0 is now the official version and 1.3.1 is the pre-release.
