The thing about Natcho is, he's no faster than Biseswar. If he were to come (and I haven't heard about this rumor at all), I'd rate his passing as being just as good as Biseswar's...so it would help take some of the sting out of our not having an attacking midfielder.
Personally, though, I don't like the idea of so many players being out of position. We had two or three years of that already; why go back? Personally, I hope Stanojevic gives the 4-3-3 a shot. Our current players' skillsets practically beg for that.
I've also heard that we're putting further GK purchases on hold. I think that's a good idea, as Melissas and Siampanis are more than adequate cover for the next six or so months.
