After the Halloween success, Niantic is prepping for Pokemon Go Gen 2. Evolution of current Pokemon and the arrival of legendary Pokemon to happen in Gen2.
It is not sure when the Gen 2 alteration will be available in Pokemon Go. But we can assume it may take a little while due to the recent successful event and its updates. The sure bet is for Christmas. It will be the Ultimate Holiday present for Pokemon Go fans. Many fans are very sad that the Halloween event is coming to an end. But the Gen 2 update will make them faint.
