I'm not one to point fingers generally, however i'd like to inform the powers that be that the probability of infinity-mods actually having any sort of xbox 360 modchip are slim.
I'd also like to bring a few other things to the table.. recently with the release of the kiosk disk, appeared a "Boot loader" disk, which was actually fake, but blatently advertised infinitymods in it's nfo.
That taken into account, also the fact that no mainstream modchip company had said a word about any possible progress or release of a new device, indicate to me that it is simply a publicity stunt to encourage visitors and rack in some sales.
If they turn around soon and say 'hey the chip we got isn't reliable so we wont be selling it' or something equally lame to get out of selling an actual chip, then do not be supprised.
"to good to be true" chips, are usually just that, i'm sure we all remember the psp modchip that would be "released on ebay soon".
All i am saying is, i would exercise caution in promoting sites that claim such big things, without any evidence.
