I'm not able to include all of them, I appended the reasons. But I have an awesome idea after this list.
Street Fighter X Tekken Vita this fall with new characters This is one news segment on a game. I would rather link to a main thread on this specific game.
Vita impressions from the community This fits. I will add it to the gaming community section.
Vita vs. 3DS vs. iPhone 4S This is an editorial from another site and is not reference.
Vita OS discussion and comparisons This is an opinion OP and is not scalable (I would need a link for each opinion OP, smthg I can't manage sadly).
Vita sales in Japan this week This is good. I have it in the Article Reference section.
Wi-Fi or 3G for Vita? Good stuff,EDIT: Added, thread includes a resourceful poll.
My idea was, for the more ethereal threads (which come and go, not official, opinion, temporary news pieces that are subject to change or only reflect an aspect of a game or subject), someone could make a Vita Repository which would contain all of those. I would link to certain solid or official Vita threads here, as well as link to that new archive, if it's made.
What do you think?
