The lower and mid-range entries in the new Galaxy Alpha family have made a live (though unofficial) appearance in Mexico. The new Alphas will prioritize build over features, which is why they are based on aluminum unibodies.
Here's the Samsung Galaxy Alpha, flanked by its upcoming siblings, the Galaxy Alpha A5 on the left and the Galaxy Alpha A3 on the right.

The Samsung Galaxy Alpha A3 will be priced a bit lower - $350-400 - and will have a 4.52" qHD Super AMOLED screen, Snapdragon 410 chipset, a 8MP/1080p camera and a 5MP selfie camera.
Not pictured is the third member of the A family expected, the Galaxy Alpha A7, which will be the top dog of the three though still not on the level of the Galaxy Alpha.
