I'm hoping to get there sometime this year, I'm from that area and have played the original courses a few times.
They wanted to use the resort to host a Canadian tour event and the courses were too short for that. But also, the two courses were so similar in style and length, there wasn't much differentiation between them, so this will probably be a welcome change. It's a bit of a shame the original architect didn't do more to differentiate them.
Also I believe they acquired additional land as well.
