GW appears to have scheduled their new revision of 40K to ship just at the end of their fiscal year. Previously they had been launching in the summer months so I can only really guess that this is an attempt to squeeze a few more dollars out of the shrinking player base to make this year look better. I guess it is also getting about time to be looking for the price rise sheet. GW got money out of me last summer with the closure of the specialist games lines but has not seen a penny since and mainline games go back more than a few years now with no purchases here (all the way back to a couple of months after the previous nid book came out last edition). FFG with X-Wing and Lego are getting my funny money now.
The rules adjustments I have seen talked about does not really have any pull with me so whatever they call it I will still probably just watch semi interested from afar.
