That is a RUMOR and is not confirmed. There has been no official mention of any firmware updates to allow dual-layer burning. In fact, the -DL burners aren't even expected until next year. Sony will, however, be releasing a +DL burner in the next month. I've already pre-ordered one for only $199. I can't believe how much the prices have dropped in the course of just a year or so. I hate the + format, but that's all that will be available for a while.

I've read the 106 supports more media types then the 107 but the 107 supports 8x writing and has already been demonstrate by Pioneer to have the ability to burn dual layer DVD's with the right firmware.
