Uuhhhmmm, to what end? The game is already out and made, and since it's not a downloadable title they can't really update it much. I'd love to be able to download a 3d version of the wind fortress in the shop or something, but I really don't think there's any need for any of the extra modes or other bits of fluff. They actually did a pretty decent job on this for the most part, so no complaints here.
Whilst i agree it was a strange decision to not include these modes, i have to admit, i'm good also. I'm happy enough with the fact the updated graphics did the original justice. Some people are just never happy.
