Yes, under the current rules it's a longer more costly process with stricter financial requirements. If you went to the US and then decided to return your husband alone would have to meet the financial requirement of making £18,600/year or more in the US for a year and have a job lined up in the UK making the same amount or more within 3 months of your return. You'd require 2 sets of spouse visas of 2.5 years each before you would became eligible for ILR and citizenship. So, you'll be paying for 2 spouse visas, ILR and citizenship and it will take you 5 years. But, in 1, 2, 3 or more years it's completely reasonable to expect there will be other changes making it an even more costly and more difficult process.
Obviously, it's your decision but if you can make it til citizenship you'll have more options and not have to worry about qualifying for a UK visa again.
