I aren't as aware of the big promises WotC made before 4e hit the shops, apart from the Online Table Top and the Visual Character builder (which is really one and the same in a way). I can see how this would be enough for people to be disappointed. Are there more things?
Thank you very much for the compliments. To answer your questions, as best I can after dealing with lots of tax issues (my gray matter is fairly mushy right now):
It really depends on what you consider a big promise. I don't particularly want to rake anyone over the coals again for past mistakes. I certainly make enough of my own. Here is a very limited list of items that were touted, then became ulcers.
From 3E/3.5E: ETools, to name one black spot on the record.
For 4E: Gleemax, and a number of items demoed at GenCon, including the VTT.
The whole issue of availability/pricing of PDFs.
Others, I'm sure, are keeping better track of such things than I.
Personally the new applications mentioned in the list, once all up in running (including and in my case ESPECIALLY including the virtual table top) would be enough for me to become a faithful suscriber. Until then I will wait. If it doesn't happen, I lose nothing.
Anyway sounds like positive news from where I'm standing. I certainly can't understand all the hate either.
A virtual setting for me to get back in touch with other old guard gamers from waaaay back? If the features met my needs (which aren't much), and was reasonably priced, then I would subscribe, too. From where I sit

the news does look positive. We'll see how the actual delivery supports or doesn't support the news.
Good gaming - no matter your edition preference!
