So, 1, 2, 3, for the millenia number. Note that the century and decade numbers go from 9's to 0's, so they'll be 1's. The one's goes 8, then 4, so probably then 2. Which means the release year would be 3112. The 3, 1's, and the 2 represent Half Life 1, 2, and 3, while the two 1's represent Half Life 2 Episodes 1 & 2.
...
Half Life 3 confirmed!
