I got a 2011 Pitch Pro back in August of 2010. I recently uploaded a picture in the main Pitch thread. Been loving the bike so far. It is my first full suspension bike so I don't have anything else to compare it to.
I think the majority of the components that come stock on the bike are good enough, especially for the price, even though I've changed a decent amount on my bike. I just mostly like to tinker with things and this is my only bike so I use it for everything. The stock X.5 shifters were working fine for me, but the X.9's definitely shift more smoothly. I upgraded them since a lot of the 9-speed stuff is very cheap these days. The stock bash guard is no good in my opinion. I'm certainly not great by any means, but I was hoping it'd be able to take a few hits. I broke it within a month. The BBG bashguard has held up nicely, is really cheap, and doesn't weigh any more than the stock. The stock wheels work fine but are a little on the heavy side. I had to get them trued more often than what I'd like, but at the same time, I'm a clyde. They may not bend as easily for the average size rider. The Roval Traverse AL wheels I put on have been working great so far and definitely make the bike feel much lighter.
Overall, I'm very pleased with the bike and it is a lot of fun. If there is one con for me, it is my height with respect to Specialized's sizing. I'm 5'11" and I bought the large. Unfortunately, I'm stuck right in between the M and L. You'll see many others on this site that are in the 5'11" to 6'2" range that are on both the M and L. I went the route of prefering to be stretched out as opposed to cramped. I shortened up my stem by 15mm and I may end up doing more. It certainly feels better for me to bring the handlebars in closer, but it definitely made the climbs slightly more difficult. The front tends to wander more (no surprise), but the decents are very nice. The only other thing I'm considering changing is the shock and fork (just personal preference here). The propedal on the shock and MoCo on the fork do their job, but I want a bit more function for the variety of terrain I see on my local trails. I can have miles of smooth single track that will dump into technical rocky sections, then back to smooth, then technical, etc... I like to keep the Propedal on and run the MoCo stiff for the smooth sections and of course it works great in the corners, but it'd be nice to have a blow off valve so I don't have to change my settings when the terrain gets technical. I'm finding the shock and fork tend to spike a lot when I hit technical areas in my usual settings. Of course, these features are removed to keep the cost of the bike down, so it is understood. For the most part, it feels like I can dial in the suspension for any situation at my trails provided I first stop. I know it can be done on the fly, but I've crashed a few times trying to do that (again, I'm not even close to being the best). I've only done 3 ft. drops and a couple 2 ft. high jumps, but the suspension feels plush and the bike feels very stable both on lift off and landing.
Interesting side note, I recently looked into the similarities of Rockshox's Sektor and Revelation fork. Seems to be the Sektor is just a stripped down version of the Revelation. I'm planning on buying the MoCo from the Revelation and putting it into the Sektor. The part is only about $85. That will give me a blow off valve in the fork. I checked with Rockshox and they said it would fit. Nice to be able to upgrade without having to buy a new fork.
