I have to disagree that it won’t be an issue. From what was disclosed so far in blogs & @ the PDC, they have said that unghosting hasn’t been eliminated… the concept does remain.
With that being said, I do agree with you Daniel that some of the major tasks that were affected by unghosting pages will be mitigated, but ~not~ eliminated. So from what I gather, it won’t be as much of an issue as it is now, but there are still cases where pages can be unghosted and yield the same challenges we face today.
We’ll prob. get more once the NDAs are mitigated when the product is released in a public beta.
