Well, its more like new and flashy results are likely because new techniques were developed or a technique was applied in a novel way. Science/Nature/etc are publishing the first results with these new techniques so of course theyre going to be a bit buggy. Subsequent refinements and discovery of systematics and how to account for them improve the research, and often change the results, but those results don't make it to Science/Nature/etc because they don't belong there (usually). So, really you should be taking the mindset that articles in these journals should be taken with a grain of salt. Whether that should have an impact on their prestige? I suppose thats a personal decision.
