I just saw this in Orange Tree's twitter feed.

Working on the chord voicing creator for the new Evolution guitar engine. What types of chords would you like it to be able to recognize?

 An improved chord voicing generator will be most welcome. Looks like they have revamped the effects and improved the mapping interface.

Yes, Greg PM'd me about this last month and he said he's working on a new engine. I do have the Acoustic steel string library, but don't really use it as it does takes a bit of work to get the desired results.
I asked him if he could make it a bit more easier (for us non-keyboardists) to get things going right out of the box....i.e EZkeys or StrumMaker IV......with the quality of OT's library would make it more desireable to use.

Sounds like there are some nice enhancements coming, and they'll (eventually) be available to existing customers free of charge. Greg says he'll implement it first in a new product, then adapt it to previous products. So it might be autumn before current EEG/EAG users see the new features.
 
The ability to scroll through presets without going to the Load dialog is a good one. There will also be new effects, so presumably new presets as well.
 
Still Kontakt 4 compatible, which is good news for me.
 
The most-anticipated feature - the improved strum editor - is probably the least important to me, since I don't use the auto-strum feature. Maybe after the update I will.
 
Now we can begin speculating what the new product will be. It'll probably be a guitar.
Possible candidates that come to mind:
- electric or acoustic 12-string (please don't be a Rick, I feel GAS just thinking about it)
- Strat or Telecaster, more likely the former
- mandolin (what could possibly benefit more from the new strum features?)

An electric 12 string, that's what I am missing!
An "Irish Bazouki" (flat backed) or an Octave Mandola would be nice, if unlikley.
 

A Banjo would be a good addition. There are a couple out there. I think
Boulder Sounds currently has the best. I would think Orangetree could top it.
