How about:  "I think Nintendo will have 95% of the under-14 yo market"

Nintendo need to differentiate from XB and PS.

That's really not a valid point. They aren't focusing on a kid's market, otherwise how would you explain games like Devil's Third, Bayonetta 2 and such on WiiU's catalogue, not to mention the 3DS games that are for over 14 year olds?

No, they're getting beaten at the market dominance because they fail to get third parties. If Nintendo could press a button and get Red Dead Redemption 2 and Manhunt 3 on their console, they would press it. They don't care about under-14 year olds in that sense, because business is business. They're just getting abandoned by third parties again, which will make them lose sales.

Besides, the main age of gamers was 32 if I remember correctly from some articles. Neglecting the biggest source of consumers when going for a market is a terrible idea, no matter how much you want to differentiate yourself.

Any announcement creates buzz and publicity. The game is a year away, hell why announce it at all this far out? Just speculating here, it of course is very likely to not have an NX future as Rockstar hasn't put its biggest on Nintendo hardware as a rule.

GTAV Release date: Sept 17, 2013
PS4 Release date: November 13, 2013

So the PS4 released after the release of GTA V.  Now on the other hand, what are the odds that RDR2 releases before the NX? Unless something goes horrifically wrong with the production of the NX - about 0%.

On top of that, R* hinted that a PS4/X1 release was immient before GTA V was out for PS3/X360. No one was surprised when it was announced for PS4/X1.So that means the NX will be out on the market, meaning R* will undeniably have full access to any type of development tools to port the game if they so choose, and as far as we know right now, R* is choosing not to use those tools to bring the game to that platform before it comes out on PS4 or X1, the same way they chose not to bring GTA V to Wii U.

it means almost nothing at this point.

A) Red Dead Redemption 2 probably has been in development for quite a while, before the NX was even solidly figured out spec wise or anything

and B) for all we know it could end up on NX and just isn't confirmed now

Nintendo has a tendency to pick and choose third party developers to work closer to and share more information with. 

bear in mind that some third party developers may not even be ALLOWED to announce games for an unannounced system. If Nintendo hasn't even released info on the NX basically at all, then why do you think anything on the platform would be allowed to be announced in advance? it makes zero sense

now obviously I wouldn't be suprised if Red Dead wasn't on the NX simply due to the last iteration not being on Nintendo platforms and it being Rockstar. But RDR2 not being announced for the NX atm is sort of irrelevant because there is no way in hell that Nintendo has given any third party publishers permission to announce games for a system that they themselves have not announced officially 

Sure it's valid:  why should Nintendo try to fight for the same customers and games as Microsoft and Playstation when they have a steady stream of parents buying stuff for kids? 

Or another way:  This site shows that it isn't possible to convince a PS4 user to buy an XB1, so how would they convince a PS4 user to buy an NX?

Red Dead Redemption was never on Nintendo consoles, iirc so why would it change now?

who cares? it will probably get a lot of mobile third party support

Your big mistake is extrapolating how this site works to how the actual consumer market works.

i hear what you're saying but you cant compare RDR2 to spinoffs and remasters. Not to mention that Xbox is getting the main games in the series anyway (except DQ)
