"Its lineup of children’s educational tablets will be upgraded to a new generation in 2013, offering advanced functionalities and rich learning experience to children between 1 and 9 years old." source
What could that mean? It could be a relatively minor upgrade like when they introduced the InnoTab 2 and 2S or it could be a new platform.
The release also mentions that VTech's strategy in this area is to "apply the latest proven technology." Well I think technologies such as Android are pretty well proven now and competitors such as Fuhu have adopted Android for their Nabi range.
My older son has an InnoTab 2 which he likes and uses a lot. But it doesn't stack up well against the Kindle Fire he also has access to in terms of responsiveness.
The requirements for a learning tablet are not the same as the requirements for a general purpose Android tablet so it's not fair to compare directly. But I imagine that VTech will need to move to a more modern platform at some point.
One of the issues for VTech is that many families have invested in the InnoTab technology so they will need to support that for a while even if they move to something new.
I'm interested to see what their plans are.
