Here's a quote (from Hunter Gordon, the bigwig in charge):
So if I read the discussion forums correctly, the big question lately seems to be 'When is T20 shipping?'
Currently T20 is undergoing the final editing to the layout. We thought we had it done week before last, but I wasn't happy with the flow of the Classes and Prior History chapters. Because of this it had to be sent back to have them redone. They were just too crammed together making it difficult to follow the flow of the text for each class or prior history.
This rework would have been complete this past week, but it was necessary to put the layout of T20 Lite ahead of it, in order that we have at least something to work with at GenCon this year! Lite is complete and at the printers currently and will meet us at GenCon. Meanwhile, the rework on T20 itself will get started again, and should be completed before the end of the week. I'll take a look at it at that point, and if nothing else seems out of place or otherwise a problem we'll pass it on to the printer.
The printer (Transcontinental) has already been prepaid and is just awaiting the final proof before getting started, but we have been warned that it may take as much as 5 weeks for the books to be run and shipped back to us here, though it is likely to be sooner. We tried threatening them with business end of an FGMP, but without a blink they reminded us that use of such a weapon in their plant would simply delay the job even longer while they waited for new equipment…some corporations just can't be intimidated.… We hope to have a more definitive date to give you once they have the T20 proof itself in hand.
