This teaser video included in the comments some rather beefy specs that have been said to be fake. "Samsung will be introduce the new Galaxy-Tab-2 Tablet at MWC-2011 (Mobile World Congress Conference on Mobile Phones) and it features Android OS 2.3 Gingerbread (upgrade 3.0 Honeycomb), 3D Display (after upgrade to 3.0 Honeycomb), NVIDIA Tegra 2 processor and rumors says a 7 inch Super-Amoled Display. We don´t think that this is real because SMD can not mass produce a 7 inch AMOLED yet. " More likely it will wait for Android 3.0 Honeycomb (hopefully) have a Tegra 2 processor, 1 gig of Ram, and the same resolution screen (but perhaps an upgraded version).
