The switch had the red and blue from launch. In the reveal trailer they only showed the grey, but then in the switch presentation they revealed the red and blue. I don't quite remember, but I think from then on they mainly used that in marketing. It could be the same situation here, but the fact that the joycons already have a hint of blue and red makes me think this will be the only version, as it's sort of a mix between the 2 versions of the original switch.

Personally I like it. I choose the grey version of the switch, and I think making the joycons the exact same colour as the system this time looks way better. Also I like the splash of colour rather than it being entirely grey/black.

I know for a fact they had the grey and colorful models on launch day, I bought the model with the red and blue joycons at mignight on launch day at my local BestBuy. The promo video in this article[1] shows some folks playing bomberman with those joycons about 2/3 in.

Not sure which version was more popular, but I bought a red/blue switch on launch day. And anecdotally I'd say I've seen more of those than the grey one over the years.
