Ok, so
1)
BENQ wasnt hacked right away because there were barelly any of them on the market.. as soon as they became mainstream (july 07) it was hacked in August-Octrober 07... (At least tahts my understanding)...
So if this drive becomes main stream, and is hackable.. i would imagine it getting hacked within 6 months.
2)
I think its too early to speculate about the chip being 1 write only etc... because if you couldnt write to it, you would be at least able to read it. Just like the console reads it. But seeing how people cant read it, means that they arent "talking" to the drive properly.. meaning we prolly need a new version of dosflash or some other utility to "talk" to the drive properly. There has to be a way to at least read the firmware.
3)
Wouldnt this promote chinese mod chip makes to make millions of dollars off of modchips for 360? Because if these drives are unmoddable and 90% of xbox's for sale have these drives.. then i wouldnt be surprised if 360's started getting chipped on regular basis.. like PS2's and Wii's do.
