Wwyd- Birthday party question

Ds is turning 4 early september. He is in nursery school and I was thinking I should invite the kids in his class. Problem is next year they won't all be in the same class , but I don't know who is going to be in it Kwim?

I can send out invites early ( if so when??) or I could push the party back ( again when?)

I would like to have a party for him but don't know what to do any advice?

I'd go with the current class since even if he has all new kids in his class come September, he won't know them yet (and chances are at least half of the kids will still be in his class)
