>USUM will be filled with content because Emerald, Platinum and BW2 were great games
Except GF is yet to show us anything that would suggest that. Recently fans have been taking GF for granted and each time GF disappointed
.>ORAS will have Emerald content
Nope
>Kalos part 2 will happen, its been like that since the beginning
Nope
>SM will be huge game filled with content because GF had a 2 year break and its the annivesary game
Nope. In fact SM was VERY underdeveloped annd unfinished. Barely any cities, closed buildings, small caves, cut out areas (like golf course), volcano with warpring entrances etc In that sense you may get an upgrade like Platinum or Emerald but not BW2 style. Also no post game. Its something that been absent in the 3ds games (unless you count 1 hour of extra storyline as post game) and its very unlikely GF had any change of heart

Also another thing
>B-BW2 also had only two months of promotion, so did Emerald
Yep, those were times when GF was doing short campaigns and wasnt revealing much.

In fact if you count the days then BW1 campaign was shorter than USUM campaign despite having new region, characters, features and over 150 new mons. Now GF makes long, worldwide campaigns and they're revealing most of the stuff. If we're not getting anything 3 months before the games come out then that means there's not much to show. Think about all the "exciting" new content they already showed. Creative designs of box mascots, creative designs of another hat pikachu and lycanroc. Amazing new Pikachu area... crazy stuff huh
