I was just wondering if there was a website that kept track of what new models or new calibers in existing models were released, and is updated periodically as new products are on the market. I haven't seen anything like this (but that doesn't mean it doesn't exist) but it would be nice to have as a resource when I'm looking to see what's changed on the market since I last looked...without having to go to each indiviudal site and hope they're up-to-date.
