I also believe errata will be free as usual regardless of frequency.
I also believe web enhancements will have to be paid for (part of their monthly fee) which is stupid especially considering that I paid for the print books.
Funny thing is 4E will be here regardless, and fanboy types will eat anything from the WotC cafeteria. There are enough of us that prefer 3.5 (basing thison reactions to the various changes being implemented in 4E), so just vote with your wallets.
Maybe with 5E, they will get back to D&D, but with WotC, Im not optimistic.
Sorry if this post offends anyone in particular.
