Yep, here is the original announcement they put out in March:
 
"GOG.com continues to build its unmatched catalogue of classic PC games  with the announcement of the deal with the famous worldwide publisher -  Atari. The hit games will be added to the GOG.com catalogue throughout  April and will include such glorious gems of yesteryear as Outcast,  Master of Orion and Master of Magic. Today, during CD Projekt Spring  Conference where the agreement with Atari was announced, Marcin Iwinski,  Co-Founder of CD Projekt and GOG.com, said "This deal is really just  the first step in what we expect will be a long and fruitful  relationship. Atari has a tremendous number of cult classics within  their grasp, and we hope to sign these in a near future!"."
And your totally right, they do release too many great games too close together. It hurts the wallet because all those 6 and 10$ games add up. I mean, releasing too many great games isn't bad... but damn money leaves quick.
