While they didn't show any continents, the coloration and angles fairly screamed out "This is Earth!" by evoking all the orbital photos we're so used to seeing (it was the perfect shade of blue). While that could just be a masterwork of misdirection, I think it would just be cheap, after giving us the false rise, to have a false fall to go with it. I'm sure they'll find Earth isn't as bad as it looks at first glance, or that another place is the nearby Promised Land, but to give us that sucker punch, and then reveal it was a false Earth? I don't like it.
