DVD+R double layer in May

Initially anounced for April, Sony will deliver its Double Layer DVD burners in May. They'll be able to burn the DVD+R (8.5GB on 2 layers) at 2.4x, and simple layer DVD+R at 8x.
Pioneer will have to act swiftly to prevent the extinction of the DVD-R. And this even more as Sony's burner will only cost 199 Euros for the internal version.
