The World Cup in South Africa has hit PartyGaming's poker business harder than expected, knocking quarter on quarter revenue by 2%, though there's excitement at the prospect of industry consolidation.Revenue, now published in euros, would have fallen between 6% and 7% quarter on quarter in dollar terms, in line with previous guidance. A 28% year on year increase, mainly due to the acquisitions of Cashcade and the World Poker Tour and continued strong growth in casino, would have been a more modest 17% using the US currency.Poker has been "particularly tough" as the number of daily average players is seen down 8-9% versus the first quarter. Reduced frequency of play due seasonality and the World Cup also led to lower yields. As such, poker revenue in euros is expected to be down between 11% and 13% quarter-on-quarter, or 15-17% in dollars.It's better news in the casino where net revenue growth is put at about 6% (up 1% in dollars), although both bingo and sports betting are flat, or down 5% and 7% respectively in American money."We are pleased with the relatively robust performance of our business compared to many other consumer facing businesses in what remains a challenging economic environment," said chief executive Jim Ryan."Overall the group has performed in-line with expectations even though the adverse impact of the World Cup on our non-sports betting verticals was slightly greater than expected."Ryan says he remains committed to "playing an active role" in consolidating the online gaming industry, and is pursuing opportunities with a number of parties.
