Dissidia is going to sell more than those two combined. Suikoden Tierkreis, in particular, looks like it's going to flop, or at least according to pre-order charts I've seen. Seems like not many people are willing to give it a chance since it's not a 'traditional Suikoden game'. For shame.
Last Tales for DS sold 100k in its first week, but since this one will be released during holidays, I expect ~150k or so.
As for Dissidia, I think some people are overestimating that one as well.
Btw, excellent article, Claude.
