With L:A, it just displayed their non-ability states since you viewed them only in "L:A" mode. They might have had their abilities listed out internally? But it would still just be the same as in L:A. if that follow sthrough to here you'd be able to view Mega data but it wouldn't display any data and if you looked under the hood you'd just see the same defaults they have now (their base form's abilities).What about Pokemon Home?
Either way Pokemon Home's update is also just "2026". My guess is that is also Early 2026 and probably meant to coincide around Champions anyway.
