Oh yes! Love your theories! I do think that land gameplay may still be a while off (its in Q1 or Q2 of 2022 in the timeline if not mistaken), and I believe that Axie Infinity Origin is more of Battles V2, which is speculated to be a improved battle gameplay system. The part I'm REALLY excited about is the card upgrades based on in-game drops; it'll be really exciting to see how it works and it may mean that those with not-so-arena-friendly Axies will get some new advantages.
