Not a keto formula but a lower carb option although 2.0 is just about right for me. (diabetic)
If possible, a move away from soy, but not so big a risk for me
As always, a drop in cost would be nice.
Parity between powdered version and the pre-mixed. As it stands, v2.0 is lower carb than v1.5 so I go with that although until I finish all of the previous powder that a friend had given me, I still have v1.x for breakfast.
Not a concern:
Solid forms - might be nice not to ship water but not really a concern of mine
Non-GMOs, organic, whatever buzzwords (free-range Soylent?)
Flavor options - people can flavor it to their liking. I think it's pretty good as is, although I did add some cocoa powder to the last batch of v1.x
Nutrient mix - I am not an expert so I cannot really judge these points
