I know I'm putting the cart waaaay ahead of the horse but I wanted to plant a seed for future development after 2E is published. Something that would really mean a lot to me and move me to adopt 2E faster would be PDF conversion guides for each of the existing Adventure Paths. My group is starting to play with the APs (we've just started RotRL and love it!) and my bucket list includes GMing all the APs before leave the Prime Material Plan for the Great Beyond :)
The APs contain such great storytelling and really you'd just need conversions for the main NPCs and monsters (though monsters may be taken care of in new Bestiaries) and possibly reference any new mechanics in 2E that should replace specific 1E mechanics. Just a thought/request.
