A pre-release e-mail signup page usually is only good for spam. But T-Mobile's Samsung Galaxy S6 pre-release page give us perhaps our clearest look at the next big thing.

Whoa. This very much lines up with Samsung's last teaser, which showed the phone in silhouette. You can clearly see the Galaxy S6 wrapped "edge" display — and we're expecting another on the other side, though this definitely doesn't look as "edgy" as what's in the Note 4 Edge — and the usual physical home button down below.

That power button on the right-hand side looks a little odd in this image — almost like it's wrapped around to the rear of the phone. We'll just have to wait a week for the March 1 unveiling at Mobile World Congress to find out.

Update: Looks like AT&T's getting into the game as well. Same teaser, same cheesy tag line, only in AT&T colors.
