I've seen no real evidence that this is Brooklyn Bridge. It *could* be, but all I saw was a ruined skyline on a coast with one tower of a suspension bridge. Why does that instantly mean it's in New York? Why not Sydney instead? Sydney's famous Harbour Bridge could fit, it's on a coast, AND it has the world's most famous opera-house.
I'm not sure they've reached Earth at all though. In the original series, the survivors mistakenly thought they'd arrived at Earth, but it turned out to be a planet called Terra. If they have reached Earth, they certainly haven't reached 'the promised land', because prophecy says that the dying leader suffering from a wasting sickness cannot enter it. Whether that's Roslin, Baltar (he was shot recently), one of the Adamas, D'Anna or someone else, they need to perish before they find what it is they've been pining after all this time.
The final ten episodes will certainly include:
1) The revelation of the Final Cylon. Baltar and Roslin are stronger candidates than ever now, since they were being held aboard the Cylon Basestar when D'Anna said that only four of the Final Five were aboard Galactica's fleet. Also, the prophecy of the First Hybrid in Razor was:
And the fifth, still in shadow, will claw toward the light, hungering for redemption that will only come in the howl of terrible suffering.
Both of them are seeking redemption, and both of them have been in a state of suffering -- Baltar was feverishly confessing his guilt in the destruction of the Colonies, after almost bleeding to death. Roslin was also trying to find peace during that episode, wracked with the guilt of the things she's done, and she's got cancer.
2) The reappearance of the other side of the Cylon civil war. The First Cylon said:
I can see them all. The seven, now six, self-described machines who believe themselves without sin. But in time, it is sin that will consume them. They will know enmity, bitterness, the wrenching agony of one splintering into many. And then, they will join the promised land, gathered on the wings of an angel. Not an end, but a beginning.
The seven he refers to are the Cylon models whose unity was shattered in their civil war. Cavil and co. are going to be led back to their brethren somehow, possibly through the influence of the Virtuals. The only character who has been referred to as an 'angel of God' is Baltar's Internal Six.
3) The explanation of the back-story and the saga of humanity and the Cylons. I suspect it's as follows:
Humanity develops on Earth, worshipping a multiplicity of gods. Monotheism replaces Hellenic polytheism. Humanity creates the Cylons, war breaks out, and the survivors abandon the planet to search for a new home. They find Kobol and rebuild, eventually coming to worship special creatures who live among them (possibly human-Cylons like Hera and Nicky). One among them seeks to primacy, and again they abandon their home. They find the Twelve Colonies, develop separately, join together until the new Cylons they've created reappear destroy them. The exodus begins and they search for a new home on Earth. The Cylons are all but wiped out on the way back too, and align themselves with Humanity, forming a new race with the more populous humans. The special ones among this number are called gods (although a small cult of monotheists exists) and humanity develops once again, and so on, forever and ever.
The eternal cycle is a constant state of flux between stillness and movement, of singularity and division, of creation and destruction.
'All of this has happened before, and will happen again.'
