What happened to Toyota in the off season?

So what did Toyota do in the off season? Wholy crap, this year Tony Stewart and his new teammate Kyle Busch finished the Nationwise series race at Daytona (formerly the Busch series) in the first and second spots for Joe Gibbs racing in new Toyota Camry race cars. And Michael Waltrip gets to start on the front row of the Daytona 500 in a Toyota Camry. Looks like Toyota has gotten their homework done with their entries into the NASCAR Sprint series and Nationwise series. They have have already been proven winners in the Craftsman truck series, so now I guess its time that they finally caught up. Seems like the Toyota race cars have a whole lot more horsepower than last year.
Congrats Toyota!
