I don't know about the name change but I have also ask a friend who is a real estate agent as to what's going on there and haven't heard back from them. If I found out anything from another source I'll post it here in answer to my own question.
Personally I think the new addition and the way they have added it on removes the possibility that Outpost will be used for a restaurant because frankly the addition is just too large and I can't imagine a new restaurant needing or experimenting on investing that much into a startup project. The only restaurant I could see possibly pulling off something like that, on that scale, and expecting it to work out would be something like Oh Bryans Steakhouse.
