Anyone can hang out in a "pro" photo forum. However, most true professionals, from portrait or commercial, usually switch cameras and equipment as seldom as possible. They're paid for competent skills with their equipment; the ablity to predictably and reliably produce the exact image desired by the client. It's virtually impossible to do that if constantly on a learning curve with the latest gadget. So this often translates into selecting a camera, learning it well, and sticking with it until forced by circumstances to change.
In other words, clients (staff, etc) at a shoot don't expect the professional to be sitting around reading an owners manual trying to figure out the latest gimmick of some new camera or whatever. In fact, they usually don't care about the equipment at all. What they do care about is the price and finished results. A re-shoot is a very undesirable extra expense. To avoid that, and deliver the results imagined by the client the very first time, the professional typically uses the equipment he/she knows and knows well.
New equipment tends to overlap the old by several months. It takes that long before a new purchase is trusted enough and familiar enough to completely replace the old. During those months, a lot of new stuff is introduced onto the market. I'm just now thinking about replacing my 18 year old Mamiya 645 with a newer medium format film camera. My four month old Pentax K10D is only just now starting to replace my two year old Maxxums on commercial shoots (Maxxums might have lasted longer had Minolta not folded). I will expect the K10D to last at least another two to three years. I might add a higher-resolution DSLR sometime next year to supplement the K10D. That equipment will probably carry me through the rest of this decade and into the next.
Finally, most professional photographers are skilled enough to be very selective about the equipment purchased. They don't buy something because the word "pro" is painted on it, a magazine calls it "pro-grade," or some manufacturer hypes it as professional. Instead, they know their needs exactly and how a new item fits into the rest of their equipment and their photography. They most certainly don't buy an item just because it is loaded with gimmicks and is expensive. In fact, since they're in business to make profits (live, buy food, etc), expensive is probably the one thing that will turn them off the quickest.
