Some new screenshots for Nintendo's upcoming port, New Play Control: Mario Power Tennis for the Wii, are now available, showing off the game's graphics (for a second time) and some of the minor changes for the Wii version.

As compared to the original GameCube version, the Wii version of Mario Power Tennis will feature motion control much akin to Wii Sports. If the nunchuk is attached, players will also be able to control their character's movement. The spin of the ball can be changed depending on the angle of the remote, and you can set the swing to perform lobs or drop shots with the press of a button. Two-player matches will also feature a split-screen mode.

New Play Control: Mario Power Tennis will release in Japan on March 15th, and will hit North America in March. You can find the official site here. Check the rest of the screenshots over at the source.
