I doubt we'll be seeing the bigger products officially so soon. Essential features, refinement of core features as well as the resource manager we are expecting that to appear in the next update if a minor update doesn't come out before.
The XF developers made it clear in the first year that their priority was to provide the best possible forum software.
It is unlikely that they will produce native addons for larger features.
Instead XF policy is to design core code which positively supports addons by secondary developers. It's designed specifically to help other developers contribute to XF.
Addons are hosted right here on the XF site making them central to the community. They are not treated as 'extra' and exiled to a separate site.
There is a native but separate addon the Resource Manager, where secondary developers list their addons.
XF moderators are excellent at supporting queries which involve addons. They even make some themselves.
XF addon developers have a very good reputation for sustained support over time so the usual concern that addons will not continue to be supported does not in general, apply.
The XF board community has always fostered a vigorous addon culture which continued to develop strongly even during the recent low period when core development stopped. Some said that it was the addon culture which kept XF going. showing that the original policy decision to make addons central to XF was even wiser than at first appeared.
There still is quite a lot of functionality to add, to allow webmasters running vbulletin Suite to migrate to XenForo. With vb5 in shambles I hope that upcoming XF releases will resolve this. Otherwise thousands of webmasters have no choice but to migrate to IPS. I believe that it would enrich XenForo as a whole to cater to this massive number of potential customers.
KAM have already proven that they are able to create essential functionality without adding bloat.
I couldn't agree more with this statement! Apps are a great alternative but if it was mobile friendly out of the box it would add so much value. So many sites now are responsive design, and a lot of internet browsing is done on mobile devices too.
Right now no blogs and gallery is one of the larger issues with moving any large vBs over to XenForo. I don't want to export that content into one of a number of XF mods because, like with vB, they'll get dropped by their developers the moment KAM come up with their own version. And we'll be left with a bunch of content that we'll again need to import back. At least the gallery bit is really essential to pretty much every community today.
