Slightly off topic but are there any plans to support more than 4 gig sometime in the near future? Maybe there is already work on this in 5-Current? Its just there are a fair few boards that support more ram these days and currently ram is dirt cheap, so it would be quite easy to go up to 8 gig in some setups, and as far as I know there is no support for more than 4 gig yet or even in the works?
