Like I wrote, Splatoon is online focused game, and games like that usually have same sort of prelaunch tests, also we only could play Splatoon only in particular time for one hour. So Splatoon definitely isn't standard type of Demo like Pikmin 3, Bayonetta 2, Falal Frame..

When people talking about Demo they usualy talking about Demo of game that they can download and play (no go to Best Buy and play, not to mention that those Best Buy Demo play exist only in US market), thats same case when we talking about Zelda U now.

Ok, I dont think Splatoon testfire was standard Demo and you dont agree, tell me than when last time Nintendo released real Demo available for Wii U users if we dont count Splatoon!? Answer is never.

My point is all Demos we have on Wii U were available only when games were officially released, not before, so there no sense to expect that Nintendo will release Demo of Zelda U next week.

Ignore dis.

Standard demo, unusual demo, rainbow demo, whatever you wanna call it, it's still a demo by definition. When someone says demo I'm gonna assume that's what they mean, not some incorrect made up definition. However, I admittedly did not pay enough attention here, as Toxy did imply he meant eShop demo. So to be more specific, yes I do think an eShop demo is very unlikely as the only Wii U game that got one couldn't be demo'd the usual way. An in-store one is quite possible on the other hand, but yeah, that's the more logical and likely idea so of course that's not what they're talking about. :L

Agree that in store Demo around E3 is posible like Nintndo already done with same Wii U games, but I dont think eShop Demo is posible before Zelda U launch and definatly not next weak.

I'd be satisfied with the release of Zelda WiiU (near the holidays most likely) and one or two eshop sales. I really doubt we can expect significant events every five years.

Metroid especially.  It's the third of the trifecta of their best series.

An eShop demo for Zelda Wii U is possible. Pokemon Omega Ruby/Alpha Sapphire had eShop demos before launch. Super Smash Bros. for 3DS did too. Bayonetta 2 and a bunch of others tha have already been listed, including Splatoon. This is not to say that it will definitely happen, it is possible that it will happen.

Regardless, do you think there are any unannounced surprises in store for Zelda's anniversary?

While I agree that Nintendo should put there other IP in the spotlight more often, I also think that this post is somewhat off topic.
An anniversary for Zelda or Spiderman if you will is bound to draw more attention to it. Those who created such an iconic series will want to put that product in the spotlight and celebrate its success. Hence why I made a thread about what has been confirmed to celebrate Zelda's anniversary, and what Nintendo might do to celebrate it further.

I can definitely imagine Nintendo doing Zelda themed DLC for other titles! This is definitely an interesting theory to speculate on. Nintendo will likely release a Zelda event course for Mario Maker that earns you a Link from Zelda Wii U outfit. What ideas did you have in mind?

Hopefully they re-release Four Swords via the 3DS. A few of my friends missed out the first time around.

New Zelda merchandise is of course always welcome.

As for Pokemon's anniversary; it will definitely be celebrated spectacularly. Hopefully they do something for Metroid this time around, it was severely ignored for its 25th anniversary. I feel like spotlight is being distributed excellently between both Zelda and Pokemon. Hopefully Metroid gets some recognition this time around.

I get Metroid, but Eternal Darkness is only one game that only core Nintendo fans know, but not many bought into, despite the praise. Wave Race hasn't been relevant since the early GameCube days. I think it could've gotten a new game since Wii Sports resort showed how motion controls could've provided a new experience for WR. Even then, it's still a small series.

Though I can think of bigger franchises like Smash Bros., DK, Mario Kart, and Pokemon that are just as well received as Metroid and sell more. Thus, Metroid, Mario, and Zelda aren't necessarily a trifecta as we usually thought before. Even then, Metriod is not necessarily a big selling franchise, selling up close to 20 million in all its games despite having a pretty good amount for 30 years. Don't get me wrong, I respect the franchise and have played some of their games, all which are pretty interesting (even Other M).
