Yes , it is final …. after so many addon Products by Invision Power , vBulletin now is coming out with its range of Official addon Products .  Quoting from vbulletin.com

Building on the plug-in architecture offered by vBulletin 3.6, the development team have been hard at work creating new products to widen the gamut of features available to sites running vBulletin.

The first of these new products are now entering the final phase of internal development and testing and will soon be unleashed. This initial batch of products consists of two applications, both of which attach to a new or existing vBulletin installation.

These products have been entirely developed by the core vBulletin development team, rather than being third-party scripts that have been bought-in and adapted, so customers can expect the same level of quality and support as they have become accustomed to with the main vBulletin Forum system.

In response to user requests we have been working on a blogging system that will fully integrate with vBulletin. vBulletin Blog (a working title) will allow sites running vBulletin to extend the functionality to allow forum users to maintain weblogs from their user control panel and leverages the extensive vBulletin permissions system to enable administrators to fine-tune the features available to their visitors.

During the development process for the new products, it became clear that it would be necessary to develop a means of managing each new product from conception to completion, and to keep track of progress on multiple projects in one central interface.
vBulletin Project Tools (also a working title) is the result of that development effort. We have been using the new tools internally for some time now and they have made significant improvements to the way we can keep tabs on how development is progressing. We intend to migrate our existing bug tracker to the new system next week, at which point everyone will be able to have a look around the system.
