Well, ThrysaM posted an intereting blog an hour ago that has since been deleted. It contained some news in Dutch, that seems to suggest that Runic Games are working on a new MMO. How accurate this is I can't say. .Here's a very rough translation, if anyone is interested. Thanks to ThrysaM for the original post.

Runic Games, the studio behind Mythos, are making a new mmog "Torchlight", which will be brought out by the Chinese editor Perfect World. The team seem to be drawing inspiration from Diablo. Perfect World will bring  Torchlight to the market. Perfect World define Torchlight as an action-mmorpg. In the game adventurers from the city Torchlight go in search of magic minerals. These minerals improve their equipment, but also endanger the advernturer. Furthermore Torchlight has a simple interface, fast action and a coloured game world. It's release date and which console it will be for are currently unknown, though it will probably be a pc title. (Bit here that wouldn't translate). The studio making the game is Flagship studios, the makers of Hellgate: London. Flagship had a separate studio in Seattle, which made the mmog Mythos. Because Hellgate: London, was a flop, Flagship were bankrupted before Mythos even saw the light. The largest part of the team in Seattle then formed Runic Games, to continue to develop mmogs. The rights to the title Mythos do not belong to Runic Games, reason why for the mmog a new title had be invented. Runic Games are, just like Flagship studios, under the guidance of Travis Baldree and (Max?) Schaefer. Baldree was the head of the Mythos team and Schaefer had a role at Flagship. He was one of the (?) of Flagship and for that also already one of the (?) of blizzard North. Schaefer worked with Blizzard for both installments of Diablo. Much of the Runic Games team come from Blizzard North.

I think it was deleted as I was about to be posting the exact same thing in English which I was writing up :P
But yeah: http://hellforge.gameriot.com/blogs/Hellforge/First-Torchlight-Details-Emerge :D
Sorry if it was one of us mods who deleted it (it wasn't me who did it, if it was one of us), hopefully it was ThyrsaM deleting it before I posted it...
Thanks for the news either way

Yeah, I figured out what happened and where and what lol, so hopefully ThyrsaM gets my PM
Thanks for bringing this to our attention again, I was a bit late on newsing it due to other stuff.
