Certainly, you can wait or you can do what I did. I special orderd mine through my friendly local FFL to get what I wanted. I have a brand new 2007 9mm 24/7 and the Distributor my FFL Dealer dealt with, had just recieved it in shipment. Distributors have had some trouble keeping the 9mm versions in stock, or so I was told.
I also would like a .45 Version of current manufacture. One of the local Gunshops is having a sale on 24/7's of all calibers, and may investigate further, to see if they have a 2007 model.
By the way, the Magazine problems of the older guns are quite fixable, by either replacement of springs or sending the older magazines back to Taurus for free replacements!
