Yeah, it seems like a simple reset isn't valuable.. makes more sense to weight the ratings over history.. so that ratings on the new version matter (much) more than ratings on the old versions.. but old ratings still count at a lower weight.. that way in your case you'd still be fine releasing a v2, but for apps that are consistently awful their rating wouldn't be so easy to pull up.
