I was about to join the squad but Todays plan is closing in a couple of months.
Should I wait until they annouce their new platform?
or do they already have one in mind?

I would wait. I think this took the entire market by surprise, EndureIQ, Purplepatch, Brownlee Fitness etc. I suspect they'll all end up migrating back to Training Peaks, but if you join today you'll have to go through onboarding twice. In the end the product will be the same I am geussing, just a lot of work for coaches to port workouts to new platform. I know today's plans offered embedded coaching videos inside sessions, that part I am not sure how they will replicate (probably external video links).

are you doing the enthusiastic or competitive plan? or are you doing the northern hemispehere work outs? My zoom meeting isnt until next week im sure itll be all explain then but just really wanted to know ahead of time.
which one did you do when you you came in 3rd place and what was your time improvement when you started using the squad.

Just super excited to get started!
