My mom (who lives kinda near there), said that they have been doing tons of work to get the buildings back up and that she's pretty sure they will be open this year. Apparently there wasn't much damage to the trees, just the buildings.
The same tornado also went down my parents road but they weren't home at the time and fortunately had no damage.
ETA: I just called them, they open Friday for the season and are open each day 10-6.
For extra fun, I think this corn maze is pretty close to the orchard as well http://www.richardsonfarm.com/
