When I was a heavy equipment operator running a D8R, D8N, and a Vermeer TG400 Tub Grinder that all used the CAT 3406, if it reached 205* all three of them would puke coolant. I find it hard to believe that that is normal and not getting hot. But on the other hand when I drove truck the W900 KW with a Detroit of some kind(430hp) would run 210-220* all day long with no problems.

This thing sounds like it's going to be a pig on fuel. I don't understand why companies are forced to reduce NVH so much. I love the sound. Infact, I see most 6.0L guys putting new exhaust on their trucks anyways, so that effectively kills the purpose in making a quiet diesel....Although 650 FT/LBS at 1600 RPM will be sweet. I'd like to see a chassis dyno of one of these things.
Drives me crazy wandering what Ford has up their sleeve, especially with this (according to Polar) GM 6.9L coming out at the same time. When does the contract that Chrysler and Cummins have end? I wander what this new Mercedes engine will be like as well.

100% agree, MB will not build a Diesel that will be accepted by the US pickup public anytime (especially Dodge buyers).
I say that, because MB is (apparently) already building a 6.0l V12 Diesel with an expected 500hp, but it will have more technology on that engine than you can poke a stick at, which will not bode well with someone who wants a big rig engine in thier pickup.
Not to mention it will cost more to build the engine, than what they sell a base Cummins equipped Ram for...

I wonder if GM is still going to handicap the manual tranny Duramax with the 300hp 520tq rating?
That GM press release said the the "new Duramax 6600 .... will be available exclusively with the new Allison 1000 6 speed...."
Also the 310 hp motor will be made thru the 3rd Qtr. With the new 360 Hp LBZ Duramax replacing it in the 4th Qtr of 2005.
This is in reference to the Silverado HD and Sierra HD

Thier lack of concentration on developing a good combo with the manual, or the fact that the other transmission option is an Allison?

That's because "down under" they still realise that even for all it's improvements, the automatic transmission is still a very delicate piece of machinery in it's own right. Don't get me wrong here, I believe the autos have come a long way, they can pull hard, are simple to use, and are much more durable than they used to be in truck applications. Still, durability is a relative term, and when you consider the overall complexity of an auto to begin with, the improvements aren't really saying much.
With a manual transmission truck, it's the engine itself which offers the most complexity of any component built into the truck - the transmission is just a simple gear box used to multiply torque at varying speeds. With an auto, you have literally a complete sub system to worry of - and one which is actually more complex than the engine itself.
I guess in Australia they follow the KIS principle- Keep It Simple ( no bothering with KISS - the last "S" which stands for "stupid", serves no descriptive purpose other than to add unneeded complexity)

Most concrete mixer trucks have automatics and I don't classify a concrete mixer truck or its auto transmission as being "delicate".

I'm going to guess that in Australia they're used more for commercial purposes. Also, the 7.3/4-spd Auto combination is still offered (no Torqueshift). Oddly, in the Cab-Chassis models, I see the 6-speed is standard, but in the 250 Supercab/Crew Cab Pickup models, the Automatic becomes standard.

Yes that would be correct, but would it be correct to say that the Chevy is not really used (often) for commercial purposes?
