Very good news (for me) regarding the 47XX upgrades. We'll have to wait to see how long it is before it's actually available though.
I can understand why the 31XX won't be upgraded, since it has limited "file store", so everything would have to be stored on a SD card, but it seems the 37XX probably should be upgradeable. I wonder if they use the same ROM so there wouldn't be a way to stop people from ruining their 31XX devices by attempting to flash them with the wrong ROM. I'm probably wrong about this, but considering the price tag of the 37XX series, I'd be disappointed if I owned one and couldn't upgrade it.
It seems to me the 47XX and the Dell X50 models were made with WM5 in mind since they have more ROM and less RAM.
