They better add the extra stuff. So they dont screw it over like they did Mario Golf and Mario Kart for GC. They took out the extra stuff in Mario Golf, like mini golf. They didnt add anything new in Mario Kart, uninspired map design, and cubical sized small battle mode maps.
So they better not screw this one over also. If they had any idea's what the fans really wanted they'd of made all 3 of these games online. But in that respect theres aboslutly no hope for nintendo because when talking about the next gen console they still say gamers dont want online play
For this game to be good, it has to have EVERYTHING MT64 had, plus loads of extra's and addictive things. but hopfully not ruin the actual Tennis gameplay with too many quirky things
