SEGA has told Eurogamer that SEGA Superstars Tennis will be out for PS3, 360, PS2, Wii and DS on 28th March.
Ellie radioed in from a press event to tell us, confirming the date listed on the mysterious Nintendo Germany schedule unearthed yesterday.
Our roving reporter in the field also confirmed that the PS3 and 360 versions will have online support, which is broken down into 9-player tournaments, friendlies, being a spectator, watching highlights and generally doing other Virtua Tennis things. Yes there is voice chat, too.
However, the Wii offering will not support online play.
The publisher also told us it was making the game with SEGA fans in mind, which accounts for it having 80 songs in from titles in its past catalogue, as well as character-themed levels like one for Alex Kidd and another for Puyo Pop.
There's a House of the Dead level as well, except its name has been changed to Curien Mansion so it can be sold in Germany, where zombies have green blood.
Ellie seemed to like what she saw, and you can have a look for yourself in our SEGA Superstars Tennis gamepage.
