My initial thought from the trailer is that it is the sort of incremental step up that we've come to expect from tech generally in the last few years, rather than anything significant. Then again, the Switch itself was pretty significant, so we probably shouldn't have expected anything else.
Still, I'm interested. I've been trying (with some success) to spend more time gaming, but it's mostly on PC with a bit on my Steam Deck. The Switch has largely passed me by because it's happened at a time when I've been busy with my kids being very young. As a result my gaming time generally has plummeted, but my console gaming has been practically non existent. I don't own a PS5 or Xbox Series X at all, when I would normally have got involved in the current generation by now. I have a Switch, but basically never play it. So yeah, might be the right time to get on board with the Switch 2 and put a few more regular hours into console gaming again.
