Seriously? Wow... makes the 32GB version even more pointless in my eyes :/
Sorry, the pro controller doesn't come packaged in the Wii U premium, for that you need to buy the Zombie Wii U premium. Anyhow, even owning the 32Gb version I imagine that anyone with "more than a passing interest in gaming" should fill up that in next to no time, so buying an external hard drive at some point seems inevitable whichever way you go.
Anyone with "more than than a passing interest in gaming" will fill up the 32GB soon enough, considering the full game downloads... practically every Wii U review has made that point. This is where using external drives comes in, meaning the difference between the 8GB and 32GB is pretty redundant in terms of storage long term. The only reason I'd consider the 32GB is for the the pro controller and NintendoLand.
I'd expect someone posting on a site called Eurogamer has more than a passing interest in gaming. The 8gb is not really the console for them...it's for the mums who don't know any better.
