G06 probably won't hit the market since...would be high priced, Ritek uses FujiFilm dye to make media for specific customers, this media costs so...
I don't know, some Canadian online stores seem to sell it: http://mirror.memoryexpress.net/
click on storage in the left hand side menu, then media, then go down to Ritek, and select the item:
Ritek 4.7GB G06 8X DVD-R, Inkjet Printable White, 50 Pack
SKU: 04893 Part No: RI-DVDR8X-IW-50
I should buy some and see if they are real... but they're in Calgary (I'm in Vancouver), and I don't like paying retail for my media
