WoW gets another expansion

I'm off on a holiday later today but as the only the only World of Warcraft addict on gamesblog - although I know Aleks has dabbled - I wanted to mention the expansion details which have emerged over the weekend. Titled Wrath of the Lich King the expansion pack - due "when it's ready" - will, amongst other things, raise the level cap from 70-80 and introduce a Death Knight Hero class. If this makes any sense to you then you are probably as excited/nervous as I am. Excited because it means hours more exploration and entertainment. Nervous because of the sheer amount of playtime needed - how long will it take to get from say level 76-77? The grind - where players have to slaughter more and more enemies to gain the experience points essential to progress - was a problem in the later levels of Burning Cusade, the first expansion. More variety in the quests would also go down well, as would the realisation that not everyone has 10-hour gaming windows available. But what am I saying? I know I'll be there, hacking/casting away with the 9-odd million others when the pack launches. Or maybe, just maybe, I'll have shaken the bug by then. Any other refusniks likely to be tempted/tempted back by the new expansion?
