Not hardly!
At the end of February bloggers speculated about this in blogs such as:
At CES 2011 Samsung introduced the new Galaxy S2 phone with a 4.3-inch wVGA RGB stripe OLED display that they refer to as Super AMOLED Plus. The horizontal subpixel dot pitch in this phone is about the same as that of the 3.1″ PenTile OLED panel introduced in products more than a year ago. There have been more than 70 mobile products that have been introduced with PenTile displays, most of then PenTile AMOLED. Many of these continue in production with PenTile OLED displays. PenTile technology remains very useful for the highest resolution AMOLED displays that are still being made.
At SID’s Display Week 2011 there was more than one new Samsung PenTile LCD display technology being shown. New PenTile products continue to be developed by Samsung.
