Sacred Stones looks to be a done deal at this point, so I wouldn't be imprudent to start now.
Is this based on insider knowledge or just from the comments here? I've seen a good number of Wario votes, so without counting anything it seems like this could still be up in the air...
Edit:Having counted the "confirmed" votes from this thread, the tally look roughly like:
Fire Emblem -- 11
Wario Land -- 8 (my vote was here, although not specified in the thread)
Kirby -- 4
There are several people who don't specify a vote, the possibility of people voting without leaving a comment, and the potential that votes could change from what was originally listed. However, Fire Emblem
probably will be the winner based on current trends.
Edit 2:The comment below is worth more than mine.
