Nintendo has posted a 30-second teaser for the upcoming Pokémon Sword and Shield that features a whole load of your favourite 'mon from previous generations. We could describe it in detail, but it's only 30 seconds - check it out above.

Neat, huh? It's great fun to see all the retro pixel versions of Pokémon from multiple generations converging and we especially enjoy seeing all the old handheld hardware getting screen time before morphing into Switches in preparation for the 'new era'.

However, it also poses a question: are all the Pokémon shown in the ad going to appear in Pokémon Sword and Shield? Following the, err, mixed reaction to the news that the game wouldn't include the entire national Pokédex with Pocket Monsters from every single previous generation, one would assume that Nintendo knows better than to tease Pokémon in a trailer that fans won't actually be able to catch in the game.

If that's the case, it's time to get freeze-framing that trailer above! Here are a few snaps to get you started:
