I don't think it will be the new kit lens, not with a starting price of just under 750 USD

Me either, although I thought it might be when the lens was first announced.

Given that - IMO - Pentax has a history of really putting its foot on the neck of early adopters price-wise, I think this is pretty good, and the street price will drop to under 7 bills fairly soon.

This lens is on B&H for pre-order it seems...

Going by B&H prices this fits in between the 18-135mm (~500 USD) and 20-40mm (~900 USD) - but closer to the 20-40mm

So will be interesting to see how it fairs against the 20-40mm

The 16-50mm seems to be 1.3k USD on B&H!

this lens has 3 aspherical elements and a 72 mm front diameter...750 is pretty reasonable, I am hoping the corner performance at the wider end is very good, if it is, it would be a perfect travel lens.

No "kit" lenses have the HD treatment, at least not yet. This lens is a bit of an anomaly, having the HD coating, DC drive and a high(ish) price. It isn't a Limited, like the 20-40, but the price suggests its IQ should be above that of the DA18-55 or DA18-135. Some test data would be in order, as I'm sure it will be, fairly soon.

From the Ricoh USA site: "In order to accommodate high-resolution image sensors in DSLRs, its MTF is programmed to be more acute than those of conventional models in the same class to deliver high-resolution, fine-detailed images."
They're setting this up as a high IQ lens--hope it meets those goals!

More light = more image quality.

More acutely programmed MTF = ?

This lens is slower then the kitlens that I got for free.

Pentax 16-85 in many aspects is very similar to Nikkor 16-85.

Since the MTF charts are provided for Pentax and Nikkor we can compare them.

HD PENTAX-DA 16-85mmF3.5-5.6ED DC WR / Standard-Angle Lenses / K-mount Lenses / Lenses / Products | RICOH IMAGING

Nikon | Imaging Products | AF-S DX NIKKOR 16-85mm f/3.5-5.6G ED VR (5.3x)

Pentax MTF looks the same or better, so we can assume that it will perform similar or better.

Photozone.de gave 4 stars out of 5 for Nikkor. Nikkor AF-S DX 16-85mm f/3.5-5.6G IF-ED VR - Review / Test Report - Sample Shots & Verdict

"Verdict

Despite some shortcomings the Nikkor AF-S 16-85mm f/3.5-5.6G ED VR DX is still one of the best standard zooms available for Nikon crop cameras. It is very sharp throughout the range although there could be a little less field curvature (curved focus field) at 16mm. The level of distortion and lateral CAs is comparatively moderate for such a lens (still a bit high in absolute terms).
Vignetting is generally well controlled except at 16mm @ f/3.5. The rather slow max. aperture may be a bit unfortunate because the achievable bokeh is rather underdeveloped in conventional scenes. If you're after a (relatively) shallow depth-of-field you should also stick to the 85mm setting - the bokeh is rather harsh at 50mm.

The VR II (Vibration Reduction) can help to safe the day in low light situations (at cost of shutter speed) with a "gain" of ~3 f-stops in field conditions. The build quality is on a good level but don't expect professional grade quality. Thanks to AF-S the autfocus is quite fast and virtually silent.

All-in-all a very good lens but not flawless."

All-in-all Pentax 16-85 looks very promising (if quality control issue is resolved).

No? It is ruined that simple though. And the quickest gain at least. Sure, the lens can have ultra magic IQ in good conditions... Only to have it ruined by the noise of the sensor under less then ideal conditions.

Perhaps not Uluru's
But in the real life, lenses aren't the sharpest wide open. And faster lenses aren't always sharper than slower ones, even at the same aperture.

When I compared the Sigma 18-35mm f/1.8 to the Sigma 8-16mm f/4.5-5.6 @ f/8 and at their widest focal lengths, the super-wide sigma lens was just as good if not better than the faster lens.

True - however with correct technique these issues can be minimized. personally I would prefer a well corrected slow lens that reached its optical peak at one stop or two from its max aperture Vs a fast optically compromised lens that needed to be stopped down several stops just to achieve consistent performance.

The F8 sample shots were sharp though, but indicative of SOOC jpegs.
