Europe's biggest telecom and entertainment group Vivendi is seen posting higher 2010 sales and adjusted net profit on Tuesday thanks to video-game unit Activision Blizzard and emerging-markets growth.

Investors will also be on the lookout for any update on Vivendi's planned purchase of Vodafone's 44 percent stake in telecoms brand SFR. Vivendi owns the rest.

Vivendi is seen posting 2010 revenue of 28.533 billion euros ($39.26 billion), an increase of 5.2 percent, according to a Reuters poll of 26 analysts. Earnings before interest, tax and amortization (EBITA) is seen up 6.3 percent, to 5.73 billion.

Adjusted net income, which excludes most non-recurring and non-operating items, is seen up 2.2 percent, to 2.64 billion.

Several Vivendi units, including Activision Blizzard and Maroc Telecom, have reported results already. SFR -- which has not -- will be under scrutiny as it is the single biggest contributor to EBITA and has come under competitive pressure from rivals like France Telecom and Bouygues.
