Here is a fresh update on where we are at in terms of hitting our schedules for the Summer of SWTOR, and a recap of all the exciting things we have in the works for the months ahead. [...]
It clearly states "for the months ahead"... As we are now in july, "months ahead" is at least august and september but could easily include october as well.
The thread states 2.3 to be on schedule for summer and 2.4 coming afterwards in october.
It really isn't rocket science to understand that.
