In a forum post two days ago - and still no sign of a blog post about it - Blizzard revealed that the price for UK subscribers to World of Warcraft is going up.
The new price for recurring subscriptions will be £9.99 for 30 days, £28.17 for 90 days, and £52.14 for 180 days. The suggested retail price of the 60-day prepaid time card will be £20.99.
Currently; 30 days is £8.99, 90-days is £25.17, 180-days is £46.14 and Amazon currently sells 60-day prepaid cards for £17.99.
The reason for this £1 increase per month is "in light of local and regional market conditions". Currently the 30-day subscription cost in North America is $14.99 - which today works out as £8.96.
However, they have some good news:
As a thank you for current World of Warcraft subscribers, we guarantee that players with recurring (auto-renewing) subscriptions at the time of the price change will retain their current price for two years, as long as they remain in the same recurring subscription without interruption.
The price change is due to happen when the new expansion - Warlords of Draenor - is released in November. Users will be emailed a reminder sometime in September about the price increase, so they can lock in the cheaper price.
