Hello @stormingrobots and @adrianmatejov,
I am very sorry for my late reply here.
The plan (as announced in the Big Changes to the Regional Representatives) is that there will be just two Soccer categories (at the international competition), that is Soccer Lightweight and Soccer Open. Soccer Lightweight will still use the IR ball, Open will play with the orange one.
Let me stress that I do understand your concerns, and your provide very valid reasons for a push for using vision, especially on the secondary level. Since the age requirements of the leagues have been removed, what @adrianmatejov mentioned above is indeed the idea behind the two categories: Lightweight being sort of an introductory league and Open the one being closer to the Major leagues. Given these constraints, at least in the interim period of this year the lightweight category will still need to use the IR ball.
Hope this helps. Please feel free to ask more questions if I missed/confused something. I'll do my best to respond in a more timely manner next time.
