1231 GMT [Dow Jones] The planned merger of online gaming, gambling and betting companies Bwin (BWIN.VI) and Partygaming (PRTY.LN) sounds extremely positive and offers "sensational" synergy effects (EUR55M annually), according to estimates from the companies, says UniCredit MIB analyst Katharina Kastenberger. She notes also that the merger will lead to well-balanced geographical presence and a very favorable product mix: sports betting 30%, poker 30%, casino 30% and gaming the remaining 10%. She maintains a buy recommendation on Bwin. Shares +18%, at EUR42.01.
