Five models of Microsoft's Surface tablet have appeared on Amazon's Germany site.
Two Windows 8 Pro Surface tablets, one with 64GB and the other with 128GB have been listed along with two Surface RT models in 32GB and 64GB capacities.
These four models were all announced by Microsoft back in June, it's the fifth model listed that seems a bit odd - as it's one that Microsoft hasn't announced.
Amazon Germany is listing a 32GB Surface Pro. If this is indeed an additional version of the Surface and not an error, a cheaper Surface Pro could really give laptops a run for their money.
