There's no guarantee that the Galaxy W is indeed a 7-inch Galaxy Mega, especially since the phone seems to sport a menu button instead of the recent apps button that Samsung is using on all its latest devices. Specs for the SM-T2558 – a 720p display, quad-core 1.2GHz processor (probably a Snapdragon 400), 1.5GB of RAM, 8-megapixel rear camera, 2-megapixel front-facing shooter, and 8GB of storage expandable via a microSD slot – are quite similar to what we've seen on the original Galaxy Mega series, but factors like that menu button and the fact that the SM-T2558 was certified while running Android 4.3 certainly make for a confusing situation.
Here's hoping more details pop up in the near future to clear things up.
