Some people are acting like this is the end of DLC, but that's not exactly the case. It's just the last video presentation specifically dedicated to Smash. Like they could still have a trailer for something down the line in a general direct.
Yeah, the wording is actually very clear on that:
"Catch the final video presentation dedicated to Super Smash Bros. for Nintendo 3DS and Wii U on Dec. 15 at 2 p.m. PT. Masahiro Sakurai will provide details on Cloud and more in this worldwide broadcast."
This doesn't rule out anything for the future of SSB4 DLC, just that it'll happen in other Nintendo directs, just like Cloud's announcement did.
If this was the END of all DLC, I'm sure they'd tell us that instead.
Also, they'd be fools to not continue to release Mii costumes because that's literally printing money. I kinda can't help but get the feeling like this isn't the end of DLC characters, either (or stages).
After all, why stop now? Yeah, balance is an issue, but it'd be MORE of an issue if SSB4 was a competitive fighting game first and a party game second, but it's
entirely the other way around.
So yeah, why shut down the money faucet now? Plus, I know for a fact that the only reason some of the Mii costumes get bought by some people is because they bundle them in a package with new fighters and stages. The bundles with new fighters are HUGELY appealing...
