I'm guessing 1.9M.
Also relying on past game kickstarters can be misleading because repeat kickstarters can be more front-loaded - e.g. see Bard's Tale IV which made 1M in day 3 but ended up with 1.5M. I'd guess all the gamers who are interested in backing on Kickstarters tend to already know about it and back on the first week, and relatively little happens later on (at least compared to previous years when it was new). I'd love to be wrong though because I like all the stretch-goals so far!
