Balancing of lens and camera body is often forgotten (I don't know why..).
Small primes made sense on film bodies because film bodies were smaller.
The limited primes made a lot of sense on K7, K5, K3 and now KP dslr series.
Now, although K1 is the smallest full frame DSLR, it is still a bit bigger than K7, K5 and K3, and the K1 body balances well with larger primes.
Slower primes for the K1 wouldn't make much sense as there is already a nice line of limited primes.
It makes sensor to design new primes lenses that balance well with full frame DSLR and take the opportunity of having a bigger size budget to max out the lens finishing and deliver unequaled optical quality.
If I look at third party lenses and lenses of other brands, they are as sharp or sharper than Pentax lenses but they kinda render pretty flat compared to the Star lenses from Pentax. We have to recognize things as they are: Pentax may be lagging behind in areas such as AF, but the Star lenses have their own beautiful rendering that no other lens can match exactly.
