Yea the Wii also launched with Zelda and similar success out the gate. However it didn't really provide much for hardcore gamers in the long run.
It'll be different this time because it will have mainline pokemon but that's not for me. I also have zero interest in Yoshi or Kirby. And their cardboard gimmick is definitley not on my radar.
They need more than the usual suspects this time to entice hardcore gamers.
Hopefully they bring back FZERO, WaveRace, Punchout and a proper gimmick free star fox and actually invest in marketing them along with the new stuff for hardcore gamers.
As a hardcore, old school Nintendo fan who has become thoroughly been disenfranchised with the company since the Wii it does feel that after Zelda it's kinda done for a bit.
I'm a bigger Metroid fan than anything but I really have zero optimism for Namco Metroid.
