GOD I hope this isn't what Retro's been working on. Maybe 3 guys AT MOST if they are though.. AT MOST.
I wouldn't count on new features you guys. These are budget-priced, remember? They don't have to justify repurchases from people who've already played them, they're going after the people who didn't own GCs using the price as the reason, and not angling for repurchases from us.
AS FOR PRICE, the Japan Price sounds just a tiny tad on the high side. Wii Sports sells there for what... 5800? Zelda: TP sold for 6800? I guess that 3800 really is sensibly priced from several angles, but in my mind that translates to $35 or $40 US and that is just ludicrous (except for Pikmin!).
I do like this idea though, especially the Jungle Beat wiimake. Jungle Beat was vastly underappreciated, and deserves a second showing to an expanded audience. As for Pikmin... original Pikmin FTW! OH I'M IN HEAVEN! That's another game that I hope becomes a more stable Nintendo franchise.
Chibi-Robo is a strange choice, but I never quite "got" the game, and for it's fans it may be in the same situation I described for Jungle Beat. The Metroids are sort of... *eh* (Maybe I'll think about rebuying the first one).
I don't get the Mario Tennis choice, does Nintendo think the core gameplay wouldn't end up changed much in a Wii sequel, so why not just re-use it already?
To be fair I don't think you could really call Miyamoto talking about the possibility of Wiimakes at some hypothetical time as "news". At best this was a rumour coming true.
When it comes from Miyamoto, it isn't a rumor.
