I have not voted yet for one reason, there should be another option either none of the above, or one really expensive lens.
Maybe I am somewhat outside the typical here, as I have shot pentax for so long that I have a rather substantial collection already.
7 primes and 7 zooms plus a 1000mm telescope. While I have a short list of fast primes that I would want, including an 85 F1.8, and the short list might win out in my vote, what I would really like is an autofocus 300mmF2.8 or a fast 500mm af lens (i.e. f4.5 or so). In writhing this, I have decided, unless someone offers either of the affore mentioned lenses for 1500, the budget isn't big enough, Ill go for the 3 lenses.
I would take either of these over the K20, at this time, as I am quite pleased with both my *istD and K10D.
My view is lenses first, as bodies will come and go as technology advances but lenses pretty much stay and have value.
Edit note, since I didn't cover the OP's question, I'll go through this now.
if 1500 is the budget, I would go for an ultra wide zoom (sigma 10-20 or Pentax 12-24) plus a fast mid range zoom, either sigma 24-70 or 24-60, or tamron 28-75, this leaves about $500 for something else,
Maybe look on the used market for a fast 50mm and a fast wide angle, or put the extra towards a very fast tele zoom (tamron or sigma 70-200 f2.8 when they become available), ot a Bigma if you want the reach. problem is these last 2 will bust the budget by about 500.
If the short end is not important you could drop the ultra wide, but I wouldn't, I use mine about 20% of the time. enough to really miss it
