One of the reasons I started the thread on community interaction is because much of the work on Touch 2.2, ExtJS 4.2 and/or 5.0 is unknown from the outside looking in. (http://www.sencha.com/forum/showthre...-the-Community)
I remember for Touch 2.0, a high-level roadmap was posted, and that was very helpful. It had the disclaimer that it could change at any time, and that was perfectly acceptable. Just having insight into what Sencha's overall goals are for the libraries is very valuable.
