Interesting stuff...although I'd like to point out (again) that I'm not *the* writer of Beyond Divinity. If anything that honour should go to Bronthion who wrote the story and original dialogues - I just came along did some editing, added a bit of me to it and some original content here and there. I'm sure I would have done things differently if I'd been involved in the early stages of story/character/narrative design.
PC RPGs are already dying out and pretty fast, that's not to say they're not flourishing on consoles, but these days for most publishers sticking to one platform for any genre is risky, especially with an almost niche genre like RPGs. I think that dialogue length will decrease in RPGs but there will be more emphasise on refining emotional character development and storytelling rather than bombarding the player with a load of text that you could of conveyed to them a hundred other ways that would have been 1) more powerful 2)less time consuming and 3) less likely to get skipped over.
