1. They don't need them. At this point they have enough evergreens that as long as they have some decent AA games they will be fine each holiday period until Switch 2 comes out.

2. Wii U and 3ds both bombed out of the gate with pathetic launch titles. Switch had Botw and SM Odyssey within months of each other, within the first 7 months of Switch's life. Those are just the two biggest examples, but they in general had a lot more content for Switch launch window and had a lot more success because of it. Therefore, they are no doubt holding next ierations of certain games for Switch 2 if my prediction of Switch 2 coming out in 2023 is correct.

2 new entries tomorrow. Will Warioware or Metroid make an appearance?

Kinda doubt Metroid will, it's not a popular franchise in Japan. 

Zelda does a nice push towards the end.

How well did the original on the Wii do?

Over 194,000 first week and over 349,000 lifetime in Japan.

Both Shin-chan & Skyward Sword heading for big openings, 

Skyward Sword HD should outsell the Wii version fairly easily, will likely end up over 500K in Japan lifetime(shipped+digital) - Breath of the Wild has really made Zelda much bigger in Japan compared to where it was as a franchise decade ago

Shin-chan is likely going to enable Neos to become a Top 10 Publisher on the Switch this year

Not bad considering the shrinking of COMG and the fact that it's just a HD remaster.

I know it's not that big but i thought it might get at least 5 preorders, that seems to be the minimum requirement to at least make an appearance in the top 20 :O

Forget about metroid, it has below zero relevance in japan. You have more chances in seeing Any cheap-ass Waifuu simulator among the top than metroid. thay are easilly able to have more sales than Dread (unfortunately).

And Skyward Sword trips at the finish line!
