Based on the last update, I guess it will not arrive in time for my daugthers 6 year birthday at the end of March. I just hope she will still find it fun to play with when it eventually arrives.
I hope that the actual physical device will make it more interesting for her, she has just finished Course 2 from http://studio.code.org and it is getting tricky as it requires rather advanced math and reading skills that she does not yet have. My hope is that in some way connect a similar interface to the Cubetto so that it can be programmed the same way you program a virtual Angry Bird Or Zombie from the courses on Code.org.
