I had that conversation in June of 2010, FYI. I know that they were looking at doing the upgrade (The COO for example was very excited about it since he deals with the operations-side on a day-to-day basis) but it was put on "hold" at around that time due to the cost concerns. Whether the project has been resumed or not since then, I do not know.
If its important to you, I recommend you ask management the status of the project during the next CC (Or email Jacky about it if you want a faster response).
