How is Google supporting Eclipse? (unless its monetary) Eclipse is Open Source....the open source community will and should continue to develop the IDE for compatability with the SDK jars that google creates.
1.0 did come out, correct. But its still in Alpha or Beta testing. There are quirks that the IDE does have that would drive some developers like me crazy. Example, if I want to put an image in the hdpi src folder, then I have to open my OS directory browser and paste it that way. In 1.0 you cant copy and paste an image into the IDE. (at least on mine...Fedora 20).
Also, when adding a new Class to your application in AS, you have to manually configure the maifest file (XML code) to add the class. In Eclipse, you still have to modify the manifest "file" but you can just simply type the class name ".NewClass" and click save in the editor....Mush faster.
I am sure that there are a lot more quirks in AS, but Eclipse is still my best recommendation.
Also, from the looks of it, It looks like AS will have pretty much the same "look and feel" of Eclipse, so when AS is ready for real use there shouldn't be that much more to learn if you are used to Eclipse.
I personally think Android Studio will be a great tool for developing android apps, But I believe also that Eclipse will continue to work
