2021 bike releases?

I have been shopping for a couple mountain bikes for me and my son. I hesitated a couple of weeks ago and now all of the bike shops are sold out of our sizes or color ways

I was looking to buy a Specialized (Chisel or Epic) or possibly a Trek Procaliber.  I had even considered a Giant.  I have been given dates from June to November for the 21 models.

Does anyone out there have any inside info for the 21 models?

Thank you,

Todd
