Last week we reported on the binary countdown clock on the new viral site for Tron Legacy, located at flynnlives.com/zerohour. The countdown clock was initally the only thing on the page, which is set to expire next Wednesday, February 24th at 8AM (PST). Just a few days later a few pixels started to show up underneath the clock, which slowly materialized into a list of 25 different cities (below).

The 25 cities are – Sydney, Denver, Madrid, Paris, Boston, Washington DC, Orlando, Atlanta, Raleigh, San Diego, New York, Philadelphia, Toronto, Austin, Minneapolis, Nashville, Chicago, Salt Lake City, Los Angeles, San Francisco, Portland, Seattle, Las Vegas, Phoenix, and London.

People around the web are throwing around their guesses as to ‘what’ exactly will be taking place in each City. Could it be a theatrical trailer premiere, or maybe a scavenger hunt of some kind in order to unlock more web based goodies, or… could it be the famed Lightcycle displays?

What do you think it could be? Let us know in the comments!

Stay tuned for the answer this coming Wednesday, on SciFiMafia.com (Luckily we’re close to one of the cities.. so, we’ll be there!)
