Yep, that pretty much sums it up. WotC policy reminds me of a boss I used to have - "My door's always open, but my mind's always closed".
The real kicker for me, aside from the fact that I feel it's "too soon" for 4E, and I believe that 3(.5) still had a few good years before a rewrite was needed, is the WotC have repeatedly said 4E was NOT designed with any concession to upgrading from 3E.
So for you folks with characters and campaigns that span years and hundreds (thousands?) of hours of loving labour, get that shredder ready, here come's the upgrade!
