I am also hoping for this bot to be able to do some chores around the house and connect to the internet wirelessly, or by usb every day to bring you updated news and entertainment information. And my last 3 wishes are that it can use the phone, talk fluently in 10 languages and speak without text to speech, or studder.
My expectations are that your expectations will not be met. About the only thing on that list that I see in the works is the wireless LAN connection.
Stair navigation? From WowWee? As a first step, they might want to make a robot that doesn't fall down a staircase when it fails to notice there's no floor to take its next step onto.
On a slightly more positive note, I think crawling up stairs, rather than walking upstairs would be an acceptable first achievement.
It takes a long time before a toddler can safely navigate stairs on their feet. Variations on hands and knees climbing, and bottom scooting are more stable ways to ascend and descend staircases. Part of this has to do with the physical size of a toddler. The stair riser is usually higher than the distance from their feet to their knees. It's very hard to step up onto something that is higher than your knee. Hoisting up the leg to put the knee on the next step is the usual technique.
The same technique is used by adults climbing uneven surfaces. When the next step up is higher than your knee, you put your knee on it, then bring up the other foot, then stand. Repeat as needed.
That means the hands are usually involved in the climbing motion, if only to steady the center of balance, if not to physically pull or push to the next level.
