Just wondering if there any upcoming 3ds games that will boost sales coming up , cause I can't think of any , Monster Hunter has released , there have been 3 zelda remakes ,  will there be a pokemon anytime soon ?, I know yokai watch is coming but anything else ?

By E3 or before Nintendo will annunced somone, probabily a Pokémon exclusive for the new version!

The new installment of Fire Emblem is no small issue. But I'm pretty sure it won't come down to it alone.
3DS might still have some three stellar years ahead of it.

Isn't this still coming out?

Fire Emblem is a big hitter for them.
I'm hoping (though doubtful for Metroid)
Maybe Pokemon Z or whatever the case.

I'm sure there will be a few others, but I'm unsure of what?

Are we forgetting Xenoblade 3DS?? If nothing moves the New 3DS, then that will.

Other than that.. nothing really sticks out until E3. I think Nintendo was hoping that STEAM would sell off until around E3, but they're dying down. I think E3 will be the boom that the 3DS needs to finish its life cycle.

Not to mention I bet a lot of third parties and IPs are making their way to the New 3DS

What happened to that Detective Pikachu game?

Probably something Pokemon.

yup Xenoblade 3DS, and Bravely second i guess.

Here's wondering what Nintendo will do with a Pokemon game exclusive to the New 3DS.. At what defining level will old 3DS systems have to make the new Pokemon have to have a faster processing system?

I think they'll wait until next year, since that's what Nintendo did with Bl2Wh2 for DS even when the 3DS launched already.

But yeah, XenobladeFTW
