I was planning to take OCA Java SE 7 exam next year, but since Java 8 is planned to be released in early 2014, the 1Z0-803 will be deprecated, and new latter exams might be appear instead.
If I would like to upgrade to OCP Java SE 8 from OCA Java SE 7, will it be even possible?
Should I wait and well prepare for the OCA Java SE 8 exam, to have the most actual knowledge?
Is there any information of when the SE 8 exams will be available(I also consider beta exam)?
The OCP exams for Java SE 5, 6 and 7 are all available right now. When an exam for SE 8 comes out, SE 7 is still going to be around for years. I would not worry about 1Z0-803 being retired any time soon.
The Java SE OCP tracks are a single exam. Therefore, if you take 1Z0-803 now... upgrading to SE 8 will be a single exam as well. Oracle only makes upgrade exams when they will save you from having to take multiple exams in a track.
I generally recommend certifying in the technology that is most relevant right now rather than worrying about one that will be the most relevant at some point in the future. Certify in 7 and once the exam for 8 is available, do that one as well.
The first notice that a beta is in the works will be when the exam appears on the 'Beta Exams' page. Oracle will not give out information prior to that:
One thing to add is that Java 8 exams are not even being discussed yet. Once a product is released, the training follows and then certification follows training, so there will usually be a gap between the product release and the certification release. Also, as Matthew mentioned, Java SE 7 is expected to be available for some time. Java SE 6 is still available.
