Emily, who has been right on the money on this so I cant doubt her this week, says that there will be more next week. This is what is says it is, a preview.
Still think it counts as an official reveal, as its also rumored (good source) that they will show off the console.
"They want to answer the biggest questions and leave you wanting more"
Will focus on what it looks like, what it does, what its called. Will also confirm use of cartridges. No hardware specs though (will come press release afterward). No lineup in that video, possibly meaning no games. Could be for whatever next week holds.
At least 3 devs are waiting for Nintendo to show off tomorrow to announce their projects.
Considering Emily's newfound credibility, may I remind you that BGE2 is an NX exclusive according to her.
