Someone from a Canadian McDonalds sent us this image of their promotion sheet for the upcoming FiM Toys scheduled for the 9th of March. I am not completely sure how similiar Canada is in comparison to the rest of us, but I'm sure some of this information will be useful for those looking to Catch em' All ™.
From last year's fiasco, it did seem like the actual toys being stocked were completely random by store. They may have buckled down a bit, but from what he tells us, we can expect the following to show up:
Shipments come every 5 days:
- Toys 1/2: Pinkie Pie and Rarity (By March 5th)
- Toys 3/4: Twilight Sparkle and Fluttershy (By March 5th)
- Toys 5/6: Applejack and Lily Blossom (By March 10th)
- Toys 7/8: Rainbow Dash and Cheerilee (By March 15th)
As with last year, you can actually purchase the toys separately, though it does vary pretty drastically from McDonalds to McDonalds. I ran into this personally last year, when one straight up refused to sell them separately, and charged a dollar each extra, and another wanted $2.50 per if you don't order anything.
As for picking specific ones, you can request it, but it really does depend on who you talk to. Mcdonalds is a busy place, so try to find them during some sort of downtime. I grabbed a Cheerilee and was told there weren't any others in stock, then returned an hour later to pick up three others.
Again though, pretty much all of this varies from store to store, so you may have to do some digging of your own.
Thanks to Peter for all the information!
