New 1.6 CDTi Diesel also for the mocha? And if so when?

I just stumbled over this article on the nethttp://www.automobil-industrie.vogel.de/produktion/articles/391102/ In this article a new 1.6 CDTI engine is described as a replacement for the 1.7 CDTI. It should be available over all model series and the production type is in the spring. Does anyone know more about it? We are about to order 1.7 CDTi automatic, but if there is soon a successor engine and possibly also with automatic, I could also wait a bit. On the other hand also somehow improbable the Opel introduced this engine quickly into the mocha or? Then there would have been the old 1.7 CDTI only a few months. Should someone know more about it ……….. Greeting MarvNRW
