SQL Server 2012 SSMS与SQL Server 2008 R2数据库引擎

I use SQL Server 2008 R2 as the database engine. With my MSDN subscription, I can get SQL Server 2012 for development use. Since I noticed some cool things in 2012 SSMS, my question is that if I only use 2012 SSMS and keep 2008 R2 as the database engine, will there be any difference in scripts' generation or any other effects?I use SQL Server 2008 R2 as the database engine
