In case you missed it: Team's Meat's teased A Voyeur for September turned out to be Super Meat Boy Forever, an auto-scrolling platformer starring everybody's favourite sentient cube of meat. Now, more details have come to light at PAX: details like it's "not an endless runner", and lots of other interesting stuff. Also the sad news that Mew-Genics—Team Meat's cat-based cat game about cats—is now on hold.
As an FAQ at the above link explains, Super Meat Boy Forever is "not a simple endless runner" and "not a one button game", but rather a meaty platformer featuring six chapters, a dark world, twice the bosses of Super Meat Boy, and "a vast randomly generated level structure" that will change the level layout after each death. There will be an endless mode, and Meat Boy will scamper along levels without you having to hold down an analog stick/d-pad, but the platforming does seem a bit more embellished than that in most endless running type games.
Team Meat's "goal with SMB:F is to design a new full length platformer for touch devices from the ground up to avoid tacking bad controls on an existing design. we want to make something that embodies the original Super Meat Boy but is designed around a simple yet intuitive control scheme allowing for pin point accuracy and surprisingly deep controls without the use of multiple buttons/analog sticks." Don't let that "touch devices" bit worry you: it's also coming to PC.
As for Team Meat's other in-development game, "Mewgenics is not canceled, we just put it on hold to work full time on this one. Once SMB:F is released we will hop back on it".
Super Meat Boy Forever looks like this:
