I have some doubts that the spin out fix is simply a new portafilter. Breville is sending me a new /B model as a replacement because the PF is consistently spinning out of my original. If a new PF alone would fix it, why not just send that instead of a whole machine?
I hope there are some changes to the group head too. I'll be rather disappointed if I can't use my bottomless or single spout PF's on the new machine without them spinning out.
the new /b machine will be tighter for the old naked portafilter you have and itwill loosen over time just like your old machine. If you use the new/b portafilter it will widen the gap more quickly and your old portafilter runs the chance of spinning out sooner. I have chosen to use my older naked portafilter for now. I asked Breville customer service if they have any naked portafilters based on the new /b desigh and they do not at the present time.
Clearly the portafilter spinning out is not a pervasive problem that affects everybody. I got mine back in mid-Dec 2011 not long after they came out.
I've had three spin outs in a year and a half and all were traceable to what Phil McKnight said about it... The silicone group gasket is slippery when wet or with soap residue from the cleaning tablets or Caffetto, whichever you use.
I just make sure the gasket and the rim of the portafilter basket is bone dry and never have a problem. In fact I only lock it lightly, not even all the way to 6 o'clock sometimes.
Some of the aussies have had some luck very lightly roughing the underside of the lugs on the portafilter. Do NOT reshape them. Just a light scuff. I have not done this as I have not needed to.

I've got a /B machine and also a /A naked PF. The /B PF screws on very tight, completely firm with the handle at 5:30 o'clock, while the naked doesn't get tight until about 4:00. So there is a difference in the dimensions of the lugs on the PF.
That said, I don't have any spinout issues with either the /A or the /B PF. But I didn't have any on my /A either, so YMMV.

We have two of these machines and have never had a portafilter spin out of place. Both machines are A models and both portafilters are of the older design. I'm not even careful to dry the portafilter edge or gasket.
My "B" model spins out very rarely compared to my first machine. However, even with drying everything carefully every time, the threat is always there so I can't leave it alone. It would be child's play to design a fix so I am not happy about this continuing potential problem. You only have to have one spin out and break a coffee cup or spread coffee fluids and grounds all over the kitchen before you develop a mistrust of this machine.
Stepping away and risking a 20 minute cleanup routine just isn't worth engaging in trust. That being said, it's a tremendous machine overall, a true bargain, and keeping one hand loosely on the portafilter handle is a small price to pay for enjoying such a great machine. After awhile I've became quite adept at single handed milk stretching/frothing.
what are you all dosing that are getting all these spin outs? I have only had that happen once and I had over tamped. Needless to say that clean up sucks ass, but I want to keep my no spin out streak alive
