Seriously though (this upstairs roight?),
I'll need to be really enticed to jump on X3. I'm not really plagued by lack of color customization (even though I'd like more of it). Take lanes are a pain but I honestly don't use them all that much because I usually get it right the first time

. All the other complaints about MIDI, automation and stuff (mostly workflow IMHO) are just not THAT big of a PITA to me.
All in all X2a gives me what I need.
I have the same wishlist I've had since X1 came out:
1. Nested folders
2. Full color customization
3. Drums maps that REALLY work
I even got about seven or eight forum members to post an enhancement request along with me for the drum map thing.
I never expect to see #1. Probably nobody but me sees it as an advantage.
I honestly expect to see some improvement #2 in X3 but it will probably not be enough for those that hate the X1/X2 paradigm.
So in conclusion even if all of the above was in X3 I'm not sure I'll be ready to justify the upgrade expense from the get go.
