Pope Benedict considering changes to celebration of the Mass?

A rumor at this point, but a notable one, claims that Pope Benedict has instructed the Congregation for Divine Worship to study the possibility of making changes to the manner in which the Mass is celebrated, including but not limited to:

• Using Latin in the Eucharistic Prayer (specifically the words of institution)
• Moving the Sign of Peace to the Offertory
• Wider use of Latin in the celebration of other Sacraments
