Zol didn't offer much in the way of detail, but the photos tell us that the i86 now sports a pair of page turn buttons to the left of the 8" screen. In comparison to the original product image, it has a decidedly lopsided appearance (which may or may not be a good thing).
According to the original specs, the i86 runs Android 4.0 on a 1GHZ CPU with 512MB RAM. It has Wifi, Bluetooth, 4GB internal storage, and a microSD card slot. The spec list also mentioned text to speech, suggesting that the i86 also has at least a headphone jack.
The 8" Pearl E-ink display has a resolution of 1,600 x 1,200. That gives it a sharpness of about 250 ppi. That's not a sharp as the 6.8" screen on the Aura H2O or the T68 Lynx, much less the super high resolution screen of the Kindle Voyage, but what the i86 lacks in sharpness it makes up for in size.
When it comes to larger ereader, the screen on the i86 is the sharpest available. And on top of the high resolution screen you'll find a frontlight and an IR touchscreen from Neonode.
In terms of ebook compatibility, the i86 supports a broad range of formats, including ebook formats like (DRMed) PDF, (DRMed) Epub, and FB2 in addition to document formats like Doc, CHM, html, and RTF. There's also support for MP3 playback. This device is running the same reading app as on Onyx's other Android-based ebook readers (with the same note-taking and scribbling abilities).
Onyx hasn't said when we might see the i86 on the market, and since we have so little information it is too early to speculate. Instead I will be keeping an eye on Mobileread Forums; Onyx sometimes posts product announcements there.
