I haven't grown Psychopsis, so I don't know about them specifically. Some people like to immediately repot any new orchid. I'm more easy going about it all myself. I don't know if Psychopsis may be fussier about when it's repotting than some other types. So, it looks like spring is a good time to repot them ... If you feel like the plant is ok as is for now, until there's new growth coming, I think that's what I would do. BUT - if someone who has experience with this genus says they aren't bothered being repotted whenever, and you'd rather not wait, go for it!
I'm going to add "Psychopsis" to your thread title in hopes some Psy growers can chime in with their opinions.
