"We'll continue to push speed and innovation - the driving forces behind Google Labs - across all our products, as the early launch of the Google+ field trial last month showed," Coughran said.
Google also clarified that it would not change in-product experimentation channels like Gmail Labs or Maps Labs. The company will continue to experiment with new features in each of its products.
