I hope they do, but have some at different sizes, we've only seen the sizes of motion and power (I think it's called - the one from imperium) so the others could be smaller
I see this as a new collection like the titan mechs. They could waver in price a little, but the cheapest i see them being is 130 least 170 most my perdiction is. 2025 january wave source dragon of water/? 130$. 2026 june wave source dragon of ice/? 130$. 2027 june wave source dragon of lightning/energy 150$. 2028 june wave source dragon of earth/strength 150$ 2028 january wave source dragon of energy/life 130$. June wave 2029 (in my opinion, the last year of dragons rising) june wave source dragon of ?/? 170$
I think we’re only going to get 6 of them because in the first episode of part 2 of season 2 (yes I was one of the people who watched it on RU-vid early) it was revealed that one of the source dragons died with the Motion source dragon telling the ninja “Someone attacked one of the source dragons, and their life was extinguished.”
Welll I because we will get all of them because ninjago loves making huge dragons and it would feel kinda weird to get one soul dragons and not get the rest
