Re the speculation about a "titanium" level based on dollars spent, weren't the "Infinates" promised that they would always be at the highest elite level? If so, CO would have to make all of the infinate platinum elites titanium elites to keep this promise. (When CO changed its highest level to platinum to match NW, the infinate golds were made infinate platinums.)
For those who were not familiar with the infinates, when CO was rebuilding in the early 1990s (I think) they offered people infinate gold if they qualified for gold for 5 years. They stopped making new infinates in 1995 or earlier.
