This is just off of Cart.com, and there is a lot of good information as to where this team(and possibly others) is headed. What it does state for sure is that Herdez will be running 2 cars in 2003, but they will not be running a second car at Mexico this year.
Anyway, it's worth a read even if you're not a big Herdez fan, it sheds some light on the dynamics of a team in our sport:
