Surface Pro Pen pressure sensitivity is not working in photoshop CS6.

This is incorrect. Microsoft will deliver this driver via Windows Update. Microsoft has taken dramatic steps in driver update deliver with Windows 7-8. You can count on it being pushed out at some point as a System Hardware Update in preparation for BUILD and the rumored announcement of Xbox Infinity, a 7 inch Surface and/or Surface Pro v2.

The Surface Pro's drivers have all been handled internally and fed out via Windows Update. There is no reason at all the pen/stylus would be any different. It being such a minor piece of the SP, it is additionally highly unlikely to cause any major conflicts. My guess is MS is testing the update package for issues before sending it out. This is in addition to the fact that MS has been chiming in for a while with updates about the beta driver and that it is being tested and that they are working on it internally.

As there was a Wacom, generic driver included in Windows for the Surface Pro that allowed the pen to function it only stands to reason that MS will deliver a package with this driver. I sincerely doubt MS will sit idly and say to the artist/designers: "Go to Wacom.com!" The SP is their product and they have so far delivered 739 fixes/patches/driver updates.

But again, why wait?

But this is the first Microsoft branded/released hardware. We won't know what their plans are unless they actually start responding and tell us.

"This isn't going to happen.  TabletPCs have shipped this way for years.  The basic driver is included, and the advanced Wacom driver is almost always separate. "

True, Microsoft doesn't have to do it the same way other OEMs have in the past, but since Wacom has released the driver already, and Microsoft hasn't said anything (If they had it might be perceived as meaning that Surface Pro users NEED this driver, which they don't.) I would be very surprised if this became part of an official MS update.  (Maybe an optional update, but I highly doubt it will be a required update.)

Like I said, they might surprise me, but I'm not going to hold my breath.  I installed Wacom's driver, and I sense that it's case-closed now.  Just my $0.02.

While I'm still pretty irritated with Microsoft for their handling of this driver, I'm definitely glad its actually come out.  I got Photoshop up and running this morning, and everything looks great.

In the future, Microsoft, for a key feature like this, give us better feedback than "Soon" then months later "Hey, we're testing a beta driver" shortly before its published on someone else's website.

I'd like to say a big thanks to everyone who basically did microsoft's job for them in this thread, getting the newest information out as soon as it was available.  I consider this thread answered at this point, but the thread itself should stick around since it shows very clearly our frustration and how exactly microsoft treats their early adopters.
