This is essentially the "brony" set, with Nightmare Moon, Trixie, Scratch, Pinkie, Dash, and Daisy. Toys R' Us has added pre-orders to their website for $39.99. If you want more stuff aimed at us, take that donation money that we seem to have endless supplies of and throw it here instead! Your collection isn't complete without Scratch and Nightmare Moon anyway!
Thanks to Ace Reporter Whatshisgame for the news as always! Dude makes Twilight Sparkle's 5 days without sleep look like a blind person trying to play Mushihimesama Futari Black Label GOD MODE Stage 5.
