About Proto-Germanic

Let’s Stick to the topic & summarise. IMO Sweden is a northern periphery of proto-Germanic continuum. Jutland is the centre.

Summarize. It is not enough to observe the presence of an elite, we must also analyze where this elite draws its status and its power. In the case of Jastorf, the answer is clear: final power stage linked to the possession and marketing of bronze. At the same time that this power lingered in Denmark, the great updating of iron had begun in Sweden. For all this see for example Hjärthner-Holdar. As for this major update, Denmark is not central but peripheral, torn between Swedish iron and that of La Tène. It is not surprising that this is where the West Germanic branch was born.

Within this scenario, Jutland and adjacent areas are West Germanic, North & East remain in Scandinavia, with a forte version of Gothic saga. 
Im open to that possibilty.
