In the linkinpark.com chat, KATHYxx and NeXus87 just solved the puzzle. Rob Walker and MCRC were instrumental in getting there, and a special shout-out to Alex, whose post also came very close to the correct answer:
A THOUSAND SUNS.
Please let me know if you think anyone else was instrumental in getting to the correct answer.
Now, please erase all the stuff you’ve filled your minds with regarding ASCII, double discs, release dates, concepts, Trinities, the Matrix, and FIRIN’ MAH LAZARS!
EDIT: It has been brought to my attention by the fans that the whole LP online community should have been thanked for participating. True; a BIG thanks to everyone for playing our game…more to come…
