Like most Pokèmon fans i was very excited when Nintendo announced the Rereleased later this year, i was excited. Like many there are more questions then answers circling around. So i am going to ask a few of them outloud.
1: Will double bikes be back (mach and acro)?
2: Will they stremline the berries like they did in x-y?
3: Will the contests be back?
4: will the fix the issues of the original ruby and sapphire (i.e restore the day night function.)
5: will it share x-y’s graphics?
6: Will out characters be customizable here as well….imagine being able to enter a contest with both you and your pokemon dressed up
7: Will they bring back the following pokemon featured in soul silver and heart gold.
8: What will they add to the game in terms of lands, will we some sinnoh in here as well? maybe another trip back to kanto and johto.
9; Will we see more pokemon become fairy’s
10: Why have they trade marked delta emerald?
11: Who else get a mega form?
those are my questions will we see answers at the upcoming e3? Only time will tell

Hopefully most of the things that were strict upgrades (graphics, customizing your character, easy berry growing) will be back. Since blaziken got a mega evolution, maybe the other starters will as well? (seems a bit unfair otherwise).
Also, secret bases! And Steven.
