News on Haswell based mobile Precision M6800 ?

No clue.

 

Don't worry, if not IPS then some other technology equal to or greater. As long as there's a market for it (that being pro) there will be an effort to fill the need.

 

Dell announces M4800, M6800 Precision laptops built for business pros

 

Here's the article from Dell:
New Dell Workstations Drastically Reduce Design and Render Times - Direct2Dell - Direct2Dell - Dell Community

[Edit]
Not much announced for the M4800/M6800, really. M4800 will have a high-resolution screen (already knew that). M6800 will have a touchscreen with 10-finger multitouch. Apparently both will support the WiGig dock and also "all-day battery life" is touted. September 12 confirmed for purchase date.

[Edit 2]
AMD Enduro support confirmed.

intredasting, nothing on IPS. waiting for DELL configurator to come up on their site.

 

The laptopmag article mentions 7200rpm w/32GB SSD cache hard drive options..

I wonder if this is just a standard hard drive with mSATA SSD cache or a will the WD hybrid drives finally show up (it was announced as an OEM option anyway)?

Only thing that seem interesting is m5100 and m6100 gpu, I hope for a 7970m fire pro version, but I doubt it ~~

m5100 sound like a big step up from m4000. M4800 probably will be the more popular choice compare to previous 2 gen. IPS, good enough gpu.
