I suppose the hope is that Nike after buying UMBRO and thus the USL league office (but not the individual teams) will put up cash to help the league rival Adidas backed MLS. It hasn't happened, there has been little talk about it lately, and I doubt it'll ever happen.
Other than that I can't really imagine what "big" move would be in the works, at least regarding rivaling MLS. Some teams wanted to require a buy-out fee for any team leaving for MLS but that didn't happen this offseason. Teams could step up and outpay MLS for 2nd tier guys coming out of college (the late 2nd and early 3rd round draft picks - the Jay Needham's) but I'm not sure that'd be "big". Something big would require a large amount of new money coming into the league.
