Besides the obvious - you already have more than enough to learn and focus on, just imagine if Elektron releases something new between now and when you’re “bored” of your two other new toys! What if they came out with an Analog-8 Poly !?
Make the most of what you just got (which is a lot), savor it, and hold out on the A4 so you can feel the rush of getting new gear, again, later on.
Hope that helps. Good luck!
