I don't mean to say they should be worried its just unusual for them to not have a huge game for the November/December period two years in a row, I'm guessing that it's likely due to New Horizon not hitting their preferred launch date and COVID probably delaying production of either Breath of the Wild or Splatoon 3 which were planned a few years ago to launch this fall.

Sans 2018, I don't think Nintendo ever had a non Pokemon title launch in November or December that was considered a big holiday game. Their games were either at the very end of October (Odyssey and Luigi's Mansion), or they forwent having a large (>5M Launch) game. 

Concerning the games that were recently announced, when will they be available for preorders in Japan?

SMT V and Metroid Dread are already available for pre-order.

Are you referring to the Yahoo shopping webstore?

Anyway, it can be pre-ordered on Amazon.

Weird.

Wonder how PS5 titles like Tales of Arise, Scarlet Nexus, Utawarerumono Zan 2, and heck, Ratchet and Clank are able to be sold/preordered at COMG if they're not in the Yahoo webstore then. 

Nice start for SMTV.

SMT5, MH Stories 2, Yu-Gi-Oh, and Summer Pockets all looking nice and healthy.
Will be interesting to see what 6 games enter the charts in three days.

SMT V is doing really good so far. Let's see if it can keep the pace.

Surprised Kimetsu no Yaiba/Demon Slayer didn't have the LE SKU chart yet.
