What do you expect to happen in this episode? Do you think Shining and Cadence will develop in this Saturday's episode, or will it just be Pinkie?
I have no idea. Let's just wait for the episode to air to find out, as always. However... From what I've seen (mostly on EqD) people seem to think that... Spoiler Skyla (Cadence & Shining kid) will become canon. Whether that happens or not... we'll see...
Since this is just speculation, I'm not gonna bother with spoilers. I think Cadance is pregnant. I also think the episode is going to be mediocre, because G.M. Berrow isn't a very good writer.
Some toy that popped up a long time ago called "Princess Skyla" that seemed to state on the toy that it was Spoiler Shining Armor's and Princess Cadence's child. I don't have the link to prove this though. Sorry.
