Until we see the proposed deeming order and regulations we don't know what's going to happen and even then there is still a comment period and time frame that the FDA has to at least pretend to consider the comments before any new regulations go into effect. Based on previous history of ecigs and the FDA the final outcome doesn't look too promising.
Honestly any new regulations will change our vaping world to some degree. We've been part of a vaping world that has been totally unregulated up to this point. I'd prefer to keep it this way but that's not realistic in todays world unfortunately.
We may need to deal with things like no on-line sales- in person sales only, no more shipping via USPS from our vendors, vendors needing tobacco licencing to sell and import licenses to purchase from China, vendors only allowed to sell tobacco and menthol flavored nic juice, standardized labeling on nic juice bottles, inspections of nic juice mixing facilities. Those are some of the minimal changes we could see if they only choose to treat us like other currently regulated tobacco products.
The worse scenario is if they apply Chapter IX of the FSPTCA to e-cigarettes. That could ban many/most e-cigarette products that were not available in the US market before February 15, 2007. Which is pretty much everything on the market today. The process to get new products after Feb 2007 approved is expensive and time consuming and ultimately up to the FDA to approve or not depending on what they feel like doing at any given moment.
It would likely be many years before anything new after 2007 was approved, IF ever. 
Our juice is the only thing that contains nicotine be it purchased in bottles or prefilled cartomizers and the only thing clearly that can be regulated by the FDA BUT following what the FDA has done in the past there is no way they wont attach wording to their regulations to attempt to regulation our atty/carto/clearos and battery holders. How much success they can have with that is questionable but no doubt in my mind they will try.
