Here's a link to their site, Polish I think www.heroesofmightandmagic.com/forgetown/
I also saw some of their work somewhere on the Heroes portal... anyway, no one from the Forge team has announced a breakup, and if you've decided to recreate Forge, that work is already being done for you. Maybe you should try joining the Forge team? If you really want to take part in creating the city of the future.
Ugh, some Turks or something broke the site! Don't go there for now.
Yeah, you're right — the guys from that topic I linked below really are making Forge, and the site's probably been hacked.
Here are a couple of pictures I managed to pull out:
