all the models Sony makes now, including the Online bundle, are + models, but you can't really tell what you'll get from an online retailer until you get the system. If you're buying from a big time retailer it'd probably be the newer model, but you can't really be quite sure unless you buy it retail and make sure yourself.
I'm planning on buying an online bundle pretty soon. My brother wants the NA out of it, and my current PS2 is a little iffy on reading discs sometimes. Plus then I can mod the current one or something fun like that.
