This interview essentially confirms that Nintendo does still care about the franchise, and are wondering what they should do with it next. They clearly realize there is a demand to keep broadening the series, but don't have any concrete plans just yet. When they asked Totilo about trying to determine which type of Metroid would like more, he basically said he couldn't choose, and that there's a place for both. We agree, and apparently so does Nintendo.
