I would as well (in the effects and features department) but I would imagine since John Nack's departure back in February, the dust is probably settling and probably had to adjust without him being there. He was a big force behind PS Touch (as well as several innovations in desktop Photoshop; Smart Objects was his baby, if I recall).
I agree, an update is well overdue, If I recall correctly, about 6 months since this last update.
And not just bug fixes (although needed I agree), but something meaty like a new tool, filter, or effect.
Please try out the update, sorry for keeping you waiting.
