A Tamagotchi that's basically normal, egg-shaped, has a key chain, does the normal functions of any other Tamagotchi-- Except it has VR/Bluetooth functionality, and when it beeps/gets hungry, wants attention, is sick and needs medicine, you pop on your VR goggles/visor, enter into your Tamagotchi's "room", or perhaps it'll have its own yard... The possibilities are legitimately endless with VR. Someday you may even be able to have sensory input pads that could simulate touch through the internet and VR. You may be able to cradle or hold, or snuggle with your Tamas!
How amazing would that be? And I believe it's 100% attainable.
