Very interesting. Somehow Marketing always places Titanium above Platinum. I think MR just abused Platinum so much that they have to use a new metal to create a buzz.
Platinum is a precious metal. Titanium is a not a precious metal, but a great light weight high strength metal. Hilton has Diamond, and Hyatt used to have Diamond, so Diamond is out.
Maybe MR will give us LT Titanium Elites a real titanium card?
