Track saw model numbers

[GoodByeDewalt]

Hello all, new user!

I am looking into purchasing a Festool track saw and have so e questions that hopefully people here can answer. I am somewhat confused about the model numbers. I thought I wanted to buy model TSC-55, but then I saw there is a TSC-55 REB. When I try to research the differences, I cant find a thread or topic that talks about said differences! Is one of these model numbers an older version?

Any help would be appreciated,
Thank Y’all

TS 55 is the orginal
E is for electronics
B is for the quickbrake
Q is for.. plug-It cord

R is the updated version, can cut closer to the wall
Newest is the F version

TSC is cordless
New version has K behind it
