5 hours? I'm already at 7 hours in Descent and not finished, and Jaws took me about 12. Mileage varies I guess.
OT: I'd love to see an announcement of a digital expansion. I mean, Edmonton team has been working on something since Jaws that involves 5 new bard songs, and obviously wasn't Descent since that has no bard songs and was made by the Austin guys. Story and companion heavy I think (the new TOR expansion indicates that Bio is headed in this direction in general). I think this is probably the likeliest option.
Less likely by far, but something I'd be excited about, would be a sort of enhanced edition for Inquisition. Now support for last-gen has been ended, it'd be fantastic to see some of the features that had to be cut for old-gen to be put back in, in a sort of mega-patch. Mounts for companions, that high level boat-burning quest in Crestwood, more cinematics throughout, a reintroduction of the DAO/DA2 tactics options etc. I'm not even remotely expecting this, well into a flight of fancy here - far too much work involved for far too little reward - but it would be great.
Personally, I'd also pay money for a sort of cosmetic pack - new presets, hairstyles, beards, moustaches, horns, freckles, scars, tattoos, new Skyhold outfits, a new option for something to wear at Halamshiral ... all with really high texture detail. This won't happen either, but I'll keep dreaming ...
Of course, it could be something far more low-key - like an announcement of the winner of the Relics of Thedas contest, or a new MP map. This would be disappointing, but it's certainly possible.
