The Pi has advantages that are not easily overcome by this:
Price: $25 for a Model A. Yes, it delivers significantly less - but at $25, it's a consumable for projects, whereas at $100 the Minnow probably isn't. $35 iff you want Network and another USB port and some more memory.
Community: If you want to do anything with the Pi, you'll likely found someone who has documented doing something very similar, and probably uploaded their source code.
Peripherals: There are a lot of them for the Pi, relatively cheap.
I think the Minnow Max will carve its own (smaller, but still nontrivial) niche, but will not actually harm RPi's market share.
