It is true that the DLP may look better motion-wise in sports, but that is not a good reason to pay that kind of money for a 720p projector even if using for Sports, and since he is more movies than sports, then the CMD3 mode on the JVC is reasonably ok for Sports (or look at the Sony hw30), and the difference isn't usually a deal breaker. I'd say if concerned, get a secondary cheaper 1080p DLP like a Mits hc4000 to pair with the JVC, because the image is close enough to the Runco in Sports/bright scenes motion (no reason to waste the money). Either that or a Benq w1200 (with it's 120hz FI and DLP motion), except the w1200 is a loser in gaming. The Runco's advantage is it does many things well and has a super sharp image and much better contrast for movies over lesser DLP's, but in most cases a 2 projector setup easily beats it overall for less money. However, if buying a JVC and a secondary DLP, the contrast issue is null and void since it has almost no effect to Sports. IF a person is RBE-sensitive, either an Optoma hd33 or a Viewsonic Pro8200 paired with the JVC is the best bet.
For 2d movies, you are hard-pressed to beat the image of the JVC, and I've seen most of the projectors (including commerical 4K Sony Projectors that cost $100,000).
For gaming, I would recommend a 2nd cheaper projector, not a Runco DLP, the operating cost is a waste of money IMHO for gaming. Gamers tend to run projectors into the ground.
FYI one correction:
The DLA-RS45 does not have a full 6-point CMS, you need an RS-55 or RS-65 for that functionality. For most people, the color on the RS-45 is good enough after a grayscale calibration, but in some yellow scenes it can be a tad over-pushed (it's not a big deal, I'm just obsessive).
