We have lots of "data" but perhaps not really "information". The net result is, it's hard for a "common resident" like me to properly understand
a) What bugs are REALLY in the queue
b) What bugs have been reported, but are not in the queue
c) What bugs are being fixed
d) When these bugs are going to be fixed.
The same applies to features...
a) What features are being considered
b) What features have been proposed, but not considered in the "near future"
c) What features are going to appear in the "near feature"
Finally:
a) How should we give feedback (beyond the official Linden Feature Discussion forum and this very same forum)
b) How can we get a timeline - understanding that this timeline is going to be dynamic - beyond some Town Hall events where either Philip, Cory or Robin give us some hints on what's going on?
For instance, I have recently read a post by Hiro - someone far more informed than myself! - asking, in surprise, if international keyboard support is really going to appear in 1.6. Searching through the Hotline, the official reply by both Robin and Ben is "it's going to be implemented very soon". However, one of the transcripts of a Town Hall I have attended shows that the promise for that is for version 1.6 - but it's hard to search for the correct transcript when using the forum search tools

Means we have the data, but not the information.
My memory is never good, but I seem to remember the following "upcoming feature list" timeline:
Late December/early January: previews on the new rendering engine (recent posts by Robin shows that this is slightly delayed, but not forgotten)
Late December or 1Q2005 (well, it looks like it won't before March

- skinnable UI on a more advanced multi-threaded viewer
- international keyboard support, notecards with Unicode characters (I even saw somewhere that they would support RTF, inline images and HTTP links!)
- inventory search, more cool inventory tricks
- large-scale login improvements, no more monolithic inventory download at login
- Linux client (!) ready 90-95% of the way, probably released later or even just with 1.7
Late Spring 2005 (since originally 1.7 should be 3 months after 1.6): Version 1.7
- Havok 2 (hah!)
- new rendering engine, including morph based animations (such as hand poses and expressions)
- new UI (not so tied into the SL client)
- 2-way XML-RPC/better object to object communication
- vastly improved in-world text support (whatever that means, I believe it's related to the new IM system), including the ability to draw things on prims - ie. playing movies or flash, font support, web pages in-world, etc.
- eventually, new permissions system (including Creative Commons copyrights)
Late 2005: version 1.8
- API for the UI
- experiments on partially open-sourcing the code (most likely just parts of the UI, not the server code - yet!)
Beyond 1.8:
- 2nd generation rendering and streaming systems
- rewriting of LSL
This list is far from complete. The sources for it are mostly from Cory's blog, Town Hall meetings, and assorted forums and posts everywhere.
However, as a suggestion I would just like to have all information at the same place! A single web site for features, suggestions, voting on suggestions, a bug queue, and, of course, a proper timeline.
