I'm more concern about the App ecosysetm than the new functionalities of BB10.
Like I posted in another thread, Blackberry now have 3 app stores, how many developers are willing to develop new and/or update apps for the Playbook app store.
Also, I have stop buying apps from the app store because of the uncertainty of BB10 on the PB. I'm uncertain if the apps that I purchase will be supported down the road if BB10 isn't coming to PB. I am uncertain if I will have to repurchase the apps if BB10 does come to PB.
I'm a big fan of the PB and a BB user for the last 9 years. I help sell over 20 PB to my coworkers and family. As a consumer, Blackberry has not given me any confidence during their product transition period. Without this confidence, it will be more tempting to switch to a different tablet with an established app store which in turn lead to a switch in phones.
