It would seem all is not well at CCP. They appear to have a Fifth Column that is trying to sabotage the next expansion, Odyssey, by intentionally misspelling it on the splash screen when the launcher appears.
Of course it could just be good old fashioned incompetence.
For those that care this was noticed on the 28th of April 2013 at 8:35am eastern Australian time.
Work out your own conversion.
* CCP fixed this about six days later. I didn't twitch very much waiting for the fix.
