Wow these are really great news. Already used Play 1.2.3 and this was already amazing easy to work with. Working now with grails 1.3.7 and I definitely will change to Play after finishing my current project. Grails is a pain and it doesnt feel very light as its built uppon the spring stack which is huge. Using plugins is sometimes risky as they are outdated and you dont really understand what they are doing in the background. I also like the type safe approach of Scala/Java which you dont have in grails(groovy/java). This is also very useful for code completion in IDEs
