I looked over the WDW February schedule for MK more carefully and found:
Mon 2/7 = 7pm SPECTRO only;
Tues 2/8 = 7pm WISHES only;
Wed 2/9 = 3pm parade only;
Thur 2/10 = 7pm SPECTRO only;
Fri 2/11 = 9pm WISHES only;
Sat 2/12 = 9pm WISHES only.
Based on this, it would appear that during slow weeks they are alternating Wishes & Spectro. And with MK open late on Wed with no EVENING spectaculars, maybe they intend spread things out a bit among the parks? If they were to put in a later Wishes/Spectro on this night, what would the attitude of non-resort guest be? If they could not enter or remain in the park after 7 and would miss an opportunity there could be many complaints. So the non-event late night must be specifically for rides!
In going over my itinerary, I have discovered that I really don't need to make very many adjustments after all. I had planned around 'non-busy' park days and, even with the possibility of 'jammed up parks' due to the 1 park-1day rule for the new passes without PH, our schedule still seems to work. This is especially nice since we have planned for Fantasmic on Wednesday evening and maybe the resort guest will be enjoying their extra 3 hours of rides and we won't have a crowded theater?
So, now our only hope of Spectro is Monday 2/7 at 7pm. If everyone else would please be kind enough to make a little room for us there we would be eternally grateful.
But, looking at the silver lining, I have never seen Spectro so, if I miss it this trip, at least I won't know what I'm missing, right?

And, no, I'm not ROFL - I am throwing a hissy-fit and going crazy.
Big group hug for all of us 'planning freaks' who are going to WDW in Jan & Feb and THOUGHT we were all set, huh?

Well, maybe after viewing your plans you will find it is not really so bad, too!
