You know guys... the last two days I was thinking about one sentence said in the Reveal announcement:
"2016 - it all comes together in an all new Pokemon adventure" -> "IT ALL COMES TOGETHER"
Now before you go: "You are thinking all regions will be available - here are 10 resons why this is unlikely" - NO, that's not what I'm thinking about! (Hardware limitations etc.)
- I'm thinking of something else - in combination with that Concept art of that Building (Hotel, Water Gym, whatever) we got.
- It shows a Trainer that looks very similar to RED - as pointed out many times!
- it is the year of the 20th anniversary of Pokemon - 20 years since RED was first playable...
WHAT IF (BIG SPECULATION - just couldn't get it out of my head):
"It all comes BACK together?"
What if - 20 years have actually passed in the Pokemon world?
Red would be 30 years by now!
We could be playing as Reds son/daughter! - and that he gave us his old adventuring clothes!
-- that's who we see in that Picture - Reds son in his old clothes!
(maybe he married Yellow - and maybe when we play as a Girl, we will have an attire similar to hers? since she never actually appeared in any game - and she is soooo cute :3)
Now disregarding any speculations on the actual location, Hawaii or Singapore or whatever , doesn't matter.
Fact is: it seems to be a tropical climate - like a holiday-resort!
maybe Red and Yellow, as a married couple, and their two twin children (both boy and girl player - the other will be one of your rivals) are actually taking a VACATION!
That Building we see is the Hotel they are staying in! (that's why that Lady has a suitcase - she is about to check in, or just checked out!)
And while the family is taking a vacation, We as the player get "bored" and set out on a Pokemon journey in this Region!
Or maybe Red got an invitation for the Pokemon League there but, gives the opportunity to his Kids, because he is now 30 and is tired of adventuring around, and he stays at the Hotel for consultantship etc.
and that would make the Hotel our "Home Town" instead of an actual town... consisting of only 4 houses^^
Oh and of course Red would be the ultimate Trainer challange post-game "Show me what you have learned, my son/daughter!" -> 'Legendary Trainer Red wants to battle!'
Again - this is all my imagination and speculation - do not take it as fact (but it would be cool if it were)
