In mine (most current version). If I select the text tool - before I click to type anywhere, go to the text options on the design central pallet and change the font, color, etc. Then type something. The next time those will be the new default.
If you just click the text tool and start typing it should use the last selected (before use) options. Same with the rectangle tool for example. I select the rectangle tool but BEFORE I click on the page to make a rectangle, use the tool options to set the fill and/or stroke color, or even make it rounded rectangle those settings will become the new default if I were to select the tool and then just make a rectangle on the page without first changing the options.
If you select one of the tools and then just start using it on the page it uses those last set of options. Changing the object properties on the page by selecting the object AFTER the object is already made will not change the defaults. Took me a bit to figure that behavior out some time back...
