What will a new Mac Pro base model not do?

The new Mac Pro will not run OS X 10.8 Mountain Lion.
Other than that, I can't think of anything.

Support 512 GiB of RAM.
Support 24 cores.
Support 88 lanes of PCIe.
Support 4 GPUs.
CUDA
You'll need a Z820 or T7610 for those....
True... but how much would that cost? I couldn't get such a configuration on the Dell site, but one close to the expected maxed-out nMP with 12-cores (2x6-core), 64GB RAM, dual GPUS, and a 256GB SSD was only $13,189.
There shouldn't be anything that it flat out can't handle, it just won't be as fast as other models.
Personally though I think the six-core model is better value overall as for the extra money you're getting an extra 4gb of RAM as standard (depends if you're planning to upgrade the RAM yourself or not), plus an extra two cores (4 hardware threads) and the D500's are more capable GPUs with an extra 2gb of VRAM. Of course if you (like me) are struggling just to afford the 4-core then it's not really an option, but it'll be able to better cope with any future demands you make of it.
But yeah, the 4-core model is still going to be a solid performer as it's not like the 4-core CPU will be a slouch by any means, and the D300's ought to still be solid for OpenCL number crunching, plus it's not as if 2gb of VRAM each is anything to sniff at.

It's a full fledge computer with a desktop OS, so it'll do everything but a tad slower than the 6-12core.
1) It won't do any of the following, nor will it occupy those spaces in my life:
Fly me to the moon
Let me play among the stars
Let me see what spring is like
On a-Jupiter and Mars
In other words, hold my hand
In other words, baby, kiss me
Fill my heart with song and
Let me sing forever more
You are all I long for
All I worship and adore
In other words, please be true
In other words, I love you
Fill my heart with song
Let me sing forever more
You are all I long for
All I worship and I adore
In other words, please be true
In other words
In other words, I love you
Songwriters

2) It, along with seemingly comparables and noncomparables by Dell and HP, won't satisfy my performance needs for the prices that satisfy me.
3) Aiden and Propower are also both correct where each states:

I've built many systems including two systems, each with quad E5-4650s (having a total of 32 cores each), and another with 8 Titans, that render 3d animations very quickly, for which Dell, HP and Apple have no similarly priced comparables or alternatives that seem priced right for me.
Yes. For me, the nMP is much to slow to do the things that I need, it costs too much for what I'd be getting (and thus I'd need to add to it and still wouldn't be satisfied), so I'd rather construct my own systems. Constructing each system has made my construction of the next one brain-dead easy and more economical.
While I'm sure the nMP would support the Apple 30" Cinema Display by placing it on top of the nMP doing so would block the air flow so I wouldn't recommend it.
I'm certain thats not what you meant though.
iThought the advantage of the 12 core MP is that all cores are on the same die!?
Cheap. Only 13 $.
Sometimes, sometimes not.
Twelve cores in a dual socket system wouldn't concentrate the heat so much, so higher clock rates could be maintained. Dual sockets support three times as much memory as a single socket, with 8 channels instead of 4 channels.
The single socket avoids NUMA memory, and the L3 cache is common to all cores.
YMMV

Will the new Mac Pros be out early Dec. (first or second week of Dec.) ?
That would sweet. I hope not the last week

Agreed on the heat concentration being an advantage of 2x6 core chips. Just look at the clock speeds of the 6 core option vs the 12 for example.
To elaborate on your cache comment, split L3 caches would be a disadvantage of a 2x6 core option. You want as many cores to have as quick of access to the cache as possible (assuming the cache amount is the same). That way if two cores are using the same data in memory, the machine doesn't need to figure out if it needs to copy the data from one cache to another. Every core has access to all the cache in the 12 core model.
The additional benefit of the 12 core CPU in the Mac Pro is that it has more cache than 2x6 core chips. The 6 core model has 12MB of cache (or 24MB if you could configure it with 2 chips), while the 12 core model has a massive 30MB L3 cache.
The hex core E5v2 has 15 MiB cache (All of the E5v2 chips have 2.5 MiB per physical core.)
Of course, these are rather small differences in cache -- and the application may or may not benefit from the larger or shared cache. It depends on the memory access and sharing patterns of the application.
