I'd expect to have the Minnesota offense show up when the Wisconsin court checks your records, so you won't get first-offender preferential treatment this time around.  It's quite possible that once you are convicted in Wisconsin, the Minnesota court will pick up on that and violate your probation or deferred adjudication, and order you to jail for that.  You need to talk to lawyers in each state, about the different court cases, for reliable advice based on all of the facts.  You can find attorneys in any state at our website, http://attorneypages.com
