Indeed.
-svy : oprobit- does seem to give correct predictions (that is, it seems to
predict probabilities, not xb's), so that is a work-around for now, as well.

Looking at the structure of the predict command under version 8, I think
the problem is that the version 9 predict routine does not properly
transform the output of _predict.
But I'm sure StataCorp will be on this quickly.
BTW, the problem affects svy: probit as well.
I bet you are right. In 8.2, there was a separate predict routine for
svylogit/svyprobit, which had special code for handling the -pr-
option. But, in 9.0, there is just logit_p.ado. So, either you need more
specialized code for -svy- in logit_p.ado or _predict needs to be
revised. (That is my wild guess anyway!)
Incidentally, I notice svy works with mlogit, so you can use it instead of
logit; but svy doesn't seem to work with mprobit. I wonder why?
