That's all the info I really found as well. Based of 360drives.com it varies..Based off the lot numbers I seen at the local Best Buy they are all going to be the newest drive, except for the 3 GOW3 consoles they have in stock.
This is from Ottawamods.ca: Dec 25/11
"Quick update to nip a few items in the bud since the questions have already started..
1. The LT+3.0 that has been released last night is for Benq and phat Liteon drives *only*. This does not work on Hitachi 78/79 or slim Liteon drives. Slim Liteon has been announced for sometime January and no ETA for Hitachi 78/79.
2. With everyone who is getting a brand new 360 this holiday season please keep in mind that not all units can be modded! If you got either a Slim 4gb, Slim 4gb with Kinect, or Slim 250gb Holiday 2011 Bundle (Comes with Halo Reach and Fable3) it's highly likely your unit can *not* be modded in any way at the moment. The only units that are still in the retail channel that likely can be modded are the super bundles (eg. Gears of War 3 or Modern Warfare 3 Bundle).
So the next logical question is how can I tell if my unit can be modded..?
Flash - Check the manufacture date on the back of the unit. The last batch of units using moddable DG-16D4S drives were made before June 2011. Units before this date should be okay but the only way to tell for sure is to open the system and look for the drive model.
RGH Jtag - Check the amperage consumption on the back of the unit. Older Trinity boards with the HANA chip that's required for RGH Jtag are listed at 12v 10.8a. Newer Corona boards use less at 12v 9.6a. Be sure to check the consumption on the back of the unit and not on the power supply since older 135watt power supplies have shipped with newer Corona systems. The cut off date was approximately August 2011."
This basically is in line with what has been discussed here and on the rest of the site. Judging from 360drive.com, MS gradually started introducing 1175 as far back as November 2010. It then, started to systematically ship consoles to different countries starting with two shipments in July and August to Bestbuy in the US, then to large department stores in most of Europe and the rest of the world -even an american airbase in Hong Kong.
I suppose, economically, it makes sense for MS to put out something like the slim and with such mass distribution. But down the road, say in a couple months, if game prices don't go down and even less games are introduced to the market, the older consoles will become more valuable as the newer slim become, well, just a pain. And nobody, not even the rich, wants to pay $50 a game in this ecomonic climate. This glut is going to cause a high supply and low demand of slim consoles, kinects and their games. It will also cause a high demand for the older modded consoles and backup games. But MS is known for their marketing genius, which leads me to believe that they're going to add something tremendous on the xbox Live side of things. But maybe I'm just talking out of my a$$.
I wonder if WiiU would be a better choice?
