Good question. I'll take a stab based on speculation.
CRJ: Someone got awarded CA recently having been with the company for 2 years. Will that be the trend? Who knows.
ERJ: Although it's not the Freedom of old (just the certificate, not the scabs) there's still a negative connotation of that word. Therefore, ERJ CA will most likely be going more junior.
Props: I really have no idea, yet they're not the 6-month upgrade of old.
That probably doesn't help, but that's all I know...or don't know.
