Elder Scrolls IV: Oblivion Profiles and Q&A

Microsoft's official Xbox website is featuring a selection of developer profiles and a short Q&A for Bethesda's Elder Scrolls IV: Oblivion. A snip from the Q&A:
Q: Do you see future RPGs lacking in the serious length department in the upcoming generation of games? Previously most RPGs ran 50-60 hours, but lately the good ones have ended on a shorter note. And why is that?

A: Length is coming down in all genres due to development time. RPGs are on the long end, and we want every hour to be good. The main Oblivion quest should take 20-25 hours. If you play all the quests it's like 200+ hours.
