Some things about the gamel (These are assumptions from the current two trailers available):
Meh things (for some at least)
There are no acres.
You must water plants.
You do have an option to make yourself your own mii.
Some positives:
ITS A NEW ANIMAL CROSSING!!!!!!!!!!
There is an entirely new area with a city along with what you have.
Wiispeak (AKA voice chat

)
Most likely, you can expand your house more and there will be more furniture, clothes, fish, bugs etc.
There is an auction house to connect with other players.
You can send letters with pictures to other people in other towns, wii message boards, computers, and cell phones.
The return of many basic principles of animal crossing.
Holidays such as Halloween, New Years, and Easter (i think) have returned!
There appears to be an actual HRA building where maybe you can get advice on your home?
Lots of personalization is still included.
Other people can come to your house from anywhere for simultaneous play.
