Why are there so few third-party games announced for switch 2?

My friend is an indie dev and told me Nintendo have not opened orders yet for non trusted partners but will soon. Meaning devs kits are just in trusted partners hands right now and Nintendo only sent those out earlier this year for some. So when they open orders for anyone to get a dev kit, more games will be announced.

Quoting this to not get lost.
