For example, for HW we are concentrating on the DL380 (Intel). We've put the DL385 (AMD) on the back burner for now because it is so different than the 380 and we need to get  a few things completely working ASAP. We'll get back to the 385 later but at least we know shark-invested waters await. I can hardly wait to see what a Dell server does.

Is not DL360 much more popular than DL380?
Also I would think that for users that deferred their VMS HW upgrades for long time both 360 and 380 would be huge overkill. Something like DL20 Gen10 would suffice.
