I have read countless posts on the forums here and over at TTG. There are absurd posts and insightful ones, but the ones that caught my attention is the subject on everyones mind. Is there another step? Looking at the code no there isn't. Most people who disbelieve there isnt another step site the code as reference. I am going to do the same thing, but to prove the opposite point. here is the section of code i want you to pay attention to. (Now its been years since my Comp Programming course, keep that in mind) Note my annotations -

If ( letter == level.passkey[ level.passkey_progress ] ) **CHECK TO SEE IF YOU ARE GETTING LETTERS IN THE RIGHT ORDER**
{
level.passkey_progress++; **IF CORRECT ORDER - ADDS TO THE PROGRESS**
if ( level.passkey_progress == level.passkey.size ) **A CHECK TO SEE IF PASSKEY IS (LUNA)**
{
flag_set( "passkey_confirmed" ); **IF IT IS LUNA THEN PASSKEY CONFIRMED**
}
}
else **NOT CORRECT ORDER**
{
level.passkey_progress = 0; **SET PROGRESS TO 0* IF NOT A PASSKEY LETTER**
}
if ( letter == level.secret1[ level.secret1_progress ] ) **SECRET 1 - CORRECT ORDER?**
{
level.secret1_progress++; **SECRET 1 - ADD TO PROGRESS**
if ( level.secret1_progress == level.secret1.size ) **IS SECRET 1 "HITSAM"**
{
**THIS IS WHERE THERE SHOULD BE CODE TO ACTIVATE SECRET 1**
}
}
else
{
level.secret1_progress = 0; **SET PROGRESS TO ZERO IF NOT A SECRET 2 LETTER**
}
if ( letter == level.secret2[ level.secret2_progress ] ) **SECRET 2 - CORRECT ORDER?**
{
level.secret2_progress++; **SECRET 2 - ADD TO PROGRESS**
if ( level.secret2_progress == level.secret2.size ) **IS SECRET 2 "HYENA"**
{
**AGAIN NO CODE TO ACTIVATE SECRET 2**
}
}
else
{
level.secret2_progress = 0; **SET PROGRESS TO ZERO IF NOT A SECRET 2 LETTER**
}
}


Now, because there is no code for secret 1 or 2 ... they do nothing (at the moment) I have tried both hyena and hitsam and NOTHING happened around the map, characters saying things, etc. I believe treyarch will hot fix the code to include something here to change what the secrets activate. The other source to disproving the continuation of the easter egg is people have noclipped and said there is nothing else to be found. It is possible (i will site the monkey buttons which actually spawns the buttons from nothing - which again is in the code) that there will be a room or some other egg that will spawn after the code has been fixed. Treyarch did this as a security against people who noclip and look through the code, After which the contigency plan of dynamically changing the egg will come to fruition.

Hopefully we can have a mature discussion on this ... if you have any questions feel free to ask.

EDIT
To clear up some confusion i am posting the part in the code that says what the lander words are.

level.passkey = array( "l", "u", "n", "a" );
level.passkey_progress = 0;
level.secret1 = array( "h", "i", "t", "s", "a", "m" );
level.secret1_progress = 0;
level.secret2 = array( "h", "y", "e", "n", "a" );
level.secret2_progress = 0;
