I was hoping this deal would also happen for previous Game Pass subscribers and here it is! There is another deal specifically for new subscribers but thankfully old (lapsed) subscribers can now get the deal too. You know the drill, lots of great games to play over the next three months. Xbox Live included for online multiplayer. Over Christmas there are usually some very decent Deals With Gold (Game specials that require gold), so for $1 you'll also get access to that.
You will get Games With Gold (Free games every month) - You get to keep Xbox One games while you have a subscription to Xbox Live Gold. You get to keep Xbox 360 games even when your subscription/s expire. Some months in the past have come with decent games. But it can be hit or miss depending on what games Microsoft chooses to give.
Includes EA Play and the Disney+ trial offer (Claim by 31/1/21. Redeem by 2/3/21).
As far as I know, Game Pass Ultimate includes Game Pass for PC, so I've added relevant details to post.
Note- it works for me and says 47 more days left to join but I'm not 100% sure it will work for all previous subscribers. Based on the comments, it looks like it usually works if you have an expired subscription, i.e. you do not currently have an active subscription. For reference, the last time I had Game Pass Ultimate was August (it was also a discounted deal). If you have had Game Pass Ultimate/Xbox Live Gold (in particular a DISCOUNTED DEAL) more recently, it most likely WILL NOT work for you - Microsoft is being generous but they do not appear to be offering it to those who have recently taken advantage of other special GPU/XBL offers.
Since there appears to be 47 days left on the offer, those with expiring subscriptions theoretically should get access to this deal when their subscription ends (if ending within the next 47 days).
It looks like plenty of ex-subscribers have been able to take up this deal. Sorry to those it hasn't worked for, presumably it has to do with how recent your last Game Pass subscription/discounted subscription/free trial/Xbox Live Gold was.

Mod: Duplicate Exception - More than 100+ votes at the time of resolving reports, so it won't be considered either way. Updated the title to 'some' lapsed subscribers, due to differing success in comments, take the lapsed subscribers part of the deal as targeted (not the new subscriber part).
