4GB yes, possible standard across the MBA line.
Do not think 8GB (one stick) is available or cheap enough.
Probably not. As much as I would like to see 4GB standard and 8GB option. I don't think we will see it in this release based on the fact the refresh will already be CPU and ThunderPort (My assumption). Cost factor for Apple have most likely increase and increasing ram as standard would probably not be favorable (while maintaining original MSRP). Also historically giving the consumer so much heavy specs is not common from Apple (at least in one iteration).
