Kind of, but not quite.
It doesn't look like we'll see the frog hop onto the arcade today, but sometime soon. Xbox.com has added the words "Coming Soon..." to it's Frogger 'recent addition' description. But coming soon could also mean tomorrow (Hey, we can hope, right?). I suppose we are lucky the outcome was not that of the recent addition Texas Hold 'Em Poker. Either way, we think it's safe to say that Frogger will be the next Xbox Live Arcade game, since the release of Uno two months ago.
Wait, what? It is a recent addition to the arcade, but it's coming soon? We know, we know.

Confuscious say I confused.
Well, yeah, it does indeed look like Frogger will be next. But then again, it looked that way with Hoopworld and, much more recently, Texas Hold 'Em. So, who knows? Microsoft? Probably not.
