The VPS updates may work for a while, but I don't know if things which changed in the program will effect the VPS which require the latest program update. AS far as would the changes be applied later, anything in the VPS would still be there when you update, so I guess they would still be available for use/instruction of 4.8.
Though I can't understand why you would want to wait, the beta went well, releasing 4 beta versions before the regular release, all of which I mentioned in my first reply and the Pros far outweigh the possible minor issues.
