I really do appreciate Conrad's cool approach.
If by "cool" you mean "apathetic". What's worse, he expects the rest of the MM fanbase to be just as apathetic, and never want Capcom to treat the series with respect. A series that many of us grew up with in some form or another, and if we feel even the slightest indignation over its current treatment, we're "entitled".
but kids aren't that critical
I'm fairly certain that yes, they are. They're not stupid; if you try to give them garbage, they'll know, and they won't like it.
They might buy/download it, but once they realize how little there is to the game, it's not likely to hold their attention for much longer.
But in case I'm giving the current generation too much credit and they really are that gormless: do you really think that the kind of person who'd enjoy Xover (in which Luka is invincible to all but the stage boss, and even then he apparently can't lose) would care for any other MM title? Those games are actually challenging, but Hypothetical New Audience is too used to easier iPhone games to care about the rest of the series.
We'll also have to wait like every other ignored Capcom fanbase. And we're not exactly being ignored.
Try that logic on the Breath of Fire fanbase, or any fans of a series that Capcom has completely abandoned save for occasional re-releases, and see how well it ends for you.
We're technically not being ignored in the sense that we're getting a dumbed-down iOS rail shooter for the 25th and virtually nothing else...but look at what Capcom's doing for Street Fighter's 25th. The SF fans get all that nice stuff, and we have to settle for Xover and an overpriced collection of music we already had for free.
