I think that you're making the mistake in thinking that people who might be buying Sports Champions already have access to or own a Wii, and therefore have access to Wii Sports Resort (seeing as you're a Wii/PS3 owner). If that was the case, then yes, I'd be hesitant to buy Sports Champions as well, seeing as they have many similar gameplay experiences.
But there's plenty of PS3 owners who don't have primary access to a Wii and want to enjoy a solid motion controlled experience. Sports Champions can offer them this, and I only see this as a good thing.
