Well I got an email today, telling me to check, (not sure why they cant put in email), seems it is out for delivery today. The update skipped all the intermediate steps, so seems like j0hn said its hit and miss.
Also yes it ends in GB, thanks for the insight.

So aliexpress has "out for delivery"
Parcelforce says its gone to normal royal mail (letters).
Royal mail says it is expected, and have the 28th as the dispatch date. (I guess when handed over to them)
If I go to aliexpress details page I then see they mark it as out for delivery just because the second courier company has the parcel so yeah very misleading, wont be getting it today.
Hopefully will have it by Friday as its the 48 hour service not 24h. So about 14 days.
