PC Gamer: "The Elder Scrolls Online hands-on: trouble in Tamriel"
http://www.pcgamer.com/uk/previews/the-elder-scrolls-online-hands-on/
Fairly decent review, doesn't smell of the usual corporate buyoff to push good reviews.
It doesn't really come across too negative or too positive, which concerns me a little. It feels to me that the reviewer didn't like it, but had to make it 'middle ground' otherwise they'd loose the ZeniMax contract.
