Yes, but I think unlockable.
Mario & Sonic at the Olympic Games, Mario & Sonic at the Olympic Winter Games, and Mario & Sonic at the London 2012 Olympic Games do not have unlockable characters. All playable characters are available from the start.
sure first was Mario and sonic at the olympic games then Mario and sonic at the olympic winter games then its Mario and sonic at the London 2012 olympic games

Mario and Sonic at the Olympic games in London. Probably. I am not so sure just yet.
Yes

Mario and Sonic at the Winter Olympic Games could be considered as Mario and Sonic at the Olympic Games 2, which would mean that the game is already released. Other than this, Mario and Sonic at the London Olympic Games will be released later on this year for Wii and early 2012 for 3DS.
