might as well be special moves you can get in the remakes, or next gen. or whatever. not everything's a hint
Most unreleased moves were released in the same generation.
Frenzy Plant, Blast Burn and Hydro Cannon was first found in RS, and it made it's way into FireRed LeafGreen officially.
Volt Tackle, also found in RS, made its way into Emerald officially.
Judgment was found in DP, however instantly recognized to be Arceus' moves, since the Hall of Origin Arceus has that move.
Arceus was first distributed officially after the release of Platinum (JP).
Freeze Shock and Ice Burn was found in Black and White, and the moves suggests the combination of Ice
and Lightning or Fire (Zekrom/Reshiram),
which was the basis of Black 2 and White 2.
So Thousand Arrows and Thousand Waves are not so obvious,
but since there are two moves, I'll say a B2/W2 repeat phenomenon is possible.
PS: One of the only moves that didn't follow this trend is V-create.
The name would suggest that it's Victini's signature move, but a Rayquaza Event from JP also received it. (Though to note, Arceus with Roar of Time, Spacial Rend and Shadow Force has been released before)
Even so, Victini isn't part of any legendary trio, so it doesn't affect the creation of a 'new game'.
