How much promotion is Darksiders getting? Ain't seen an advert or anything for it here in the UK. It's pretty much on every last review site going though, so my guess is THQ are really trying to push the game through internet media as oppose to TV and such like.
But yeah, both are going strong. Got to say I'm impressed how THQ are turning themselves around at the moment. Bayonetta isn't doing poor though, it's Japan + USA + Europe first weeks are going to add up to 600k+ in the end.
My only worry is both games will have their legs chopped off, Janaury isn't the strongest month for sales and theres alot more heading to the market.
