News about the S4 is coming out next week and the next diff jump is coming (14% or more) you may want to consider it...
EDIT:Here's the post it's not much but something.
Dear Mister BitMan,
We need to know when to expect the S4

Absent news it's time to buy SP31s.
Dear Miasma,
We are waiting for testing results of the S4 sample machine. Hopefully there will be good news before next Tuesday.
