Mars Odyssey Ready to Tackle Science Agenda
"We’ve got a number of other high-priority targets that are of great interest to people in general," Saunders said. Those include the top of Olympus Mons, Valles Marineris, and the so-called 'Face on Mars – a site that some claim to be of artificial nature."
"We’re going to try to cover all that in the first month or so, and release the data immediately…and just get it out there,' Saunders told SPACE.com."
"There’s always a sense, true or not, that we’re not getting it [data] out fast enough. It’s not always the fault of any particular investigator or mission. It just has to do with planning and money," Saunders said. "We’re going to try and solve that by giving out what may be the most interesting stuff in general as soon as we can,' he said."

I also was disappointed as was Bob WIlliams that they did not release any visible light color images on the first release on March 1st.
My speculation: the responsible scientists want first crack at the images before releasing them to the general scientific community.
