The news stories that appeared this week on many sites concerning Nikon's resumption of camera building in Thailand are basically due Nikon's releasing an official statement. There wasn't really anything in that press release that wasn't already known and reported here earlier other than the the projected loss of sales due to the flooding.
As I reported last month, Nikon resumed some DX DSLR and lens production at a temporary plant in Thailand and has begun work on restoring the main plant, which should begin building cameras and lenses again in January and be at full capacity again by the end of March.
In terms of DX DSLRs, it appears that D3100 inventory is meeting demand. NikonUSA seems to be delivering D5100 bodies of late, though supply of that camera is slightly restrained. The camera that's in short supply is the D7000--most dealers I talk to report not getting their full orders of this item in the past month, but are getting some. The D300s appears to be completely out of stock and not in production; I've heard no reports of D300s bodies being delivered from NikonUSA recently.
That's likely to remain true through the end of the year: D3100 will remain available, D5100 will be a little tight, D7000 will be very tight, and D300s will be MIA. DX lenses seem to be in slightly better shape at the moment, but we could see some tightness in supply there, too.
At this point I don't expect any new DX products from Nikon before March or April of 2012, though there is one lens that was about to be launched at the time of the flood who's status is now unknown.
