I've exchanged several PMs with pokey9000 today. He has taken a look at the software update packages for both the 2nd generation KF and the 7" HD. The MLO (xloader, 1st stage bootloader) is signed and the boot header is the type used for HS (high security) OMAP devices with the M-Shield turned on. If the setup is comparable to the Nook Tablet, this is not good news for those hoping to modify these devices in one way or another. The Nook Tablet's exploit was to utilize the external sdcard as an alternate boot device and that doesn't really help with these 2nd generation KFs.
It's all subject to verification by someone who has a device in hand, but it doesn't look good. This is not to say that it's impossible, but it will be considerably more difficult to manipulate these devices than their 1st generation cousin.
So, let's all hope for the best, but be prepared for the worst. If you plan to buy one of these devices, buy them as an Amazon tablet to be used in the Kindle Fire ecosystem. Don't buy them expecting to run Jelly Bean the day after tomorrow.
