No, the real question is: If you think you have a use for the Pi 2, why haven't you bought some other arm board yet? The Pi 2 specs look a lot like a Cubieboard 2 or a Cubietruck. Granted, these are more expensive, but the Pi 2 is also quite late on the market. So unless you have serious funding problems the niche the Pi 2 could fill should already be filled.
