Pfff!! If it comes with a bigger hard drive, plus even brings games with the bundle, paying a bit more is worth it, rather than going for a version with lesser space. Take the PS3 for instance, I went for the one with the biggest space (don't recall which one it was) and the same applies for the WiiU, you have the normal and the deluxe version, while it's 50€ more, you get more space and also brings other benefits (which I don't really recall).
What I mean is, if you're going to buy a system, you might as well get the one with the most stuff, even if it's slightly more expensive, I actually deem the expensive versions as the real versions whereas the cheaper ones are pretty much for people that don't plan to do much with them (like seriously, could you download anything with the cheapest version of the 360?)
