No no no, no pulldown! Renoise will just have one button in the middle of the screen “Song generate”, after pressing you can save as wav or mp3 of your choice. A very important tip, before pressing SG you have to pray for which genre you want, you need to be a high Renoise believer or else it won’t work!!
The list Jonas wrote contain most of the requested features, if these get implemented what is left for V3? 
No nibbles, but a nibbles API so you can write your own nibbles.
No filename generator, but a filename scripting engine so you can launch scripts to name a file.
Embedded smilies in the pattern editor.
Rss feed in the sample editor.
Fortune teller at launch time, every fortune has the word ‘penis’ in it.
The Kaneel TV Network, All Kaneel, all the time.

Homeland security terror alert, next to the sample offset marker in sample editor.
Online poker.
From the top of my head… 
Arranger

PDC
Audio freeze (or to be more precise, ability to have large wav files and have them playing from wherever you decide to start playing the song)
Tempo Envelopes (perhaps it’s allready possible ?)
Midi export
Script Support
Pimped up xrni
Midi quantization/Count In
Linux version
Movable/Detachable GUI parts
A smapler! A full featured one.
- Native Midi Export
- Linux Version (then I can finally dump Windows)
- Multilayered Samples (import of KONTAKT and BATTERY stuff)
- Arranger
- Sample Streaming (simply for vocals RAM is not enough)
- Count in
On the other hand, I love this babe it is
Sampler??
Renoise pretty much IS a giant sampler as it is…
What more could you possibly need??
Mixdown button.
Multilayered Samples. Samples with different key velocity. More effects samplewise. Import of “professional” sample-banks so no vst is needed for that 
So this would partially be a revision of the Instrument format I guess…
Made me lol…

A BtPD. (Meta-device :> )
