I been following the Teaser speculations closely for the past few days.
Today it was speculated that the "numbers" 4, 15, 16, & 23 are some how related to the "LOST" TV show. The numbers used in the show are: 4, 8, 15, 16, 23, & 42.....Ok that we know.
I did some research based on the LOST concept and found something which I think is most intreguing.....
If you follow this URL: http://www.lostpedia.com/wiki/Unanswered_questions
to the unanswered LOST question and scroll down to the botton, you will notice what "looks like" the "Runes" Blizzard is illustrating to us on the Splash Teaser....keep in mind the concept or metaphor. A few symbols with octagon like figures around them. Their are quite a few at the bottom.
Now also, one of those "unanswered questions" leads to the a "DHARMA Initiative"....
Now follow this URL: http://www.lostpedia.com/wiki/DHARMA_Initiative
On this page, notice there is a "Symbol" or as Blizzard would lead us to believe; a "Rune" that says HYDRA!
Now follow this URL: http://www.lostpedia.com/wiki/The_Hydra
The HYDRA here is listed as a Station with an "Underwarter" section.....Also if you look at the upper right hand corner of the page, it has the HYDRA in a "Rune" concept that Blizzard is using to show us the "Runes" on their Splash Screen. Also, note in the "NAME" reference category at the bottom that is says this....
"The word HYDRA also means "Any persistent or ever-increasing evil with many sources and causes""
This leads me to believe, based on everyone else's insights that Blizzard is trying to imply with the "Splash Screen Teaser" that they're going to indeed announce the HYDRA PROJECT at WWI....Why?
Look at the Splash Screen once again...."Perhaps" it is the "Unanswered Question" (From the 1st URL above) "HYDRA PROJECT" breaking through the Frozen Water, or Tundra, Cavern, etc (The names of the CSS jpgs) that is being illustrated to us!! I think what looks like steam is "Boiling Water" mist...
Could this hidden "Purple Character" be a HYDRAS????
........Now this doesn't exactly say what HYDRA is....but we can surely expect an announcement this weekend if everything continues to fall into place. Unless they throw us a bone tomorrow haha.
