I want to get a new (cellular) iPad before I travel for a few months in late April, and I'm wondering when you think the next update will be? March/April or next fall? I currently have an iPad 3 (Wi-Fi), but I'm considering the iPad mini for increased portability on the road. I don't need a new one right now, because my current iPad meets my needs for the time being, but I'm wondering when the next update might be to try to determine if I should pick one up now or just wait until April in the event of an update. Thanks in advance for your thoughts.
