I havent heard of anything new, but he was always an interesting story.... i was never 100% convinced wither way but it was still very intriguing
Have you perused the johntitor.com site of late??
There was a recent Coast to Coast ep that covered John on Monday, April 4, 2011 - 1AM EST/10PM PST -
Patent Application US20060073976 was filed for a Method of Gravity Distortion and Time Displacement. The filing date is listed at October 1, 2004 by Marlin B. Pohlman of Tulsa, Oklahoma. The application includes the identical images posted by John Titor online, as well as the time travel theory he discussed.
The above content is from the main site posted above and i think you can listen to Coast 2 Coast show as well.
As i said i don't buy it totally but it is still an interesting story either way
