Well, I think I got it finally.
They had hidden it quite well, but not from me!
You should roll the name of "The elder scrolls V" around a square or 4x4.
SETVCLHERDEROLLS
Then change all the vowel letters to 1 and the rest to 0, which results in:
0100=40001=10010=21000=8
This means 4 years, 1 month, 2 days, and 8 hours after their last elder scrolls related release, they would release TES-V.
The shivering isle was released in (27 Mar 2007) for PC, so TES V would be released at (29 Apr 2011) for PC.
See? That was easy.
