Fair enough, we clearly have different perceptions on this. Yes Blizz push out polished games and deserve a lot of respect for that, also if they have retained the support of the battlenet community.
But 3 years for the second part of a story, generously 5 years for the lot (a not very complex or particularly innovative story - sure they lazily plagiarise across their own IP's) is way too long to hold my avid attention. Like i said, i've no doubt i'll play them, but reckon i'll hold off until they are complete. Whats the hurry, eh Blizz?
Oh and then theres that general vibe that its all going to end perfectly to setup World of Starcraft (Titan). Aye ok this is speculation but it was detectable in WC3 and panned out to be true.... main characters just not dying when they really should - that is, if story trumps merchandising & future sales.
