According to this article, three companies placed a bid for the delivery of ten diesel locomotives to PKP IC. The companies involved were Vossloh España, Newag and PESA. In the end, PESA had the best bid, and thus will be supplying PKP IC with the ten diesels from 2015.
MainlineDiesels.net: PESA only has the Gama electric locomotive operating test services at the moment, so these passenger diesel locomotives seem to be a new development. The PESA website mentions the development of 2200 kW diesel locomotives, which are based on the Gama platform and have a maximum speed of 140 km/h. If the PKP IC locomotives will have these specifications as well, still remains unclear. Some sources speak of 2200 kW and 160 km/h in stead.
