While you are right that there are a few Evas that were never made by Bandai, they have given Eva pretty good coverage in terms of the sheer number of toy and model lines made.
We've had three model lines for Eva from Bandai, LM, HG and one PG IIRC.
On the toy front from Bandai, we've had: HCM-Pro, SOC , SPEC, countless gashapon and wasn't there at least one GFF style figure?
Eva will probably never get as much coverage as Gundam from Bandai, despite it's popularity, as there are simply not a large number of different mecha to make. Most of the Evas are simply a head swap and repaint with different weapons.
Back on topic.
Placed my preorder for the two of the 1/100 Alto VF-25 yeserday. Looking forward to this. My only concerns are beeing able to keep track of all the small parts and whether the peg-in-hole joints will hold up over multiple transformations.
Worst case one gets displayed permanently in fighter,the other in battroid.
