Ruger has just announced a new .45 Redhawk revolver. It's chambered for .45 ACP and .45 Long Colt cartridges. The Redhawk is equivalent to a Smith & Wesson "N" frame, and in this case a direct competitor of the S&W 625.

The cylinder is cut for moonclips when shooting .45 ACP which gives me a warm and fuzzy feeling. If IDPA still had an ESR division this would be a great choice. It would still be a fine choice for shooting USPSA revolver at major power factor and still be competitive. I don't have any use for the .45 LC feature, but to each their own, and it's always nice to have options. I have created a frankengun with my 625, so this would be ideal if I needed a stock gun rather than bring mine back to a factory form.
I'm disappointed at the listed MSRP (in fact I'm still recovering from sticker shock), but I suspect street price will be much lower. A .45 moonclip gun isn't what I need at the moment, but if this is a sign of things to come, an 8-shot .357 may be on the horizon. If so, Ruger can go ahead and take my money!
