Are you "worried" about the LTD for the Q4 titles or just the Q4 sales? Let's see the battles (LTD):
Pokemon S&M vs Pokemon US&UM - S&M will win by a landside (let's hope US&UM can reach 2 million)
Yokai 3 Sukiyaki vs Yokai Busters 2 - Is Busters 2 two different SKU like the first one? I see Busters 2 selling 500.000 LTD so I think this battle is going to be close
Mario Party Rush Hour vs Mario Party the Top 100 - Top 100 is going to win

Jikkyou Powerful Pro Baseball Heroes vs Attack on Titan 2 - Another close one. I see Titan reaching 100.000 LTD even if you don't expect it.
Miitopia vs Girls Mode 4 - 3DS expected life could play against Girls Mode legs... but should be another close one.
Animal Crossing vs Kirby - This I don't know because I haven't been following the Kirby title and I don't know what to expect from it. 300.000 LTD could be too much or not?
Super Mario Maker 3DS vs Mario & Luigi RPG DX - Yep, another no contest. Let's see if M&L can sell more than 10% of Mario Maker's LTD.
The problem is third party games (MH Stories & Momotaro Densetsu) and of course a big Nintendo title like Mario Maker last year. But all in all not a bad holiday line up I'd say.
