Of these, Wario, Rhythm Tengoku, and Starfee are new. The other two were announced before, but have not been fully detailed by Nintendo -- something that will presumably change now that they have release dates.
While third party titles weren't included in Nintendo's announcement today, one company did announce a date for a high profile DS title. Square Enix will release Sigma Harmonics, its fusion of mystery-adventure story telling and RPG battles, on August 21.
All these dates are for the Japanese market only at the moment.
