Go Red Sox, from a life-long fan!
You have hit the nail on the head when you mention Nikon's presence in the field of advertisement. Simply put, Nikon & Canon spend a lot of money on advertisement, whereas Pentax relies heavily on word of mouth. Pentax is a niche market of sorts.
The up side of this is the cost of your Pentax DSLR is not stuffed with advertising costs, though production is certainly more costly since they handle much smaller numbers.
Again, we all must bear in mind it is not about the best camera system; it is about the best camera system for the user. Pentax has a lot going for it--no doubt about it!
