If I had to guess...based on how the Hornet has developed...
We'll get the F-16 into Early Access with about half of the systems in place, but everything critical already done.
Aim-9M/9X, JHMCS/HMCS, Litening Pod (Since the A-10 already has it), GBU's and JDAM's and Harms but no HTS at first.
As EA goes on we'll get Sniper, HTS and such.
Personally, as I said before, I'd have preferred a Block 40 Viper, but the 50 will be a hoot anyway. A Block 52 would have been fun as well, but I understand why ED wouldn't have done that.
