No way it will be that soon. They have only just announced a partnership, to get the phone out for Q1 they would have to have devices and software in testing now. The problem with anything new is that will be "step 1 of 5" all over again...
It seems clear that Nomovok have had some inside knowledge of Tizen in advance and are working with Intel on it. This is why they could announce so quickly. This does not mean that the Tizen platform is particularly open in general.
No, it's terrible news. There's absolutely no incentive for anyone to develop for this platform1), because popular platforms like Android, iOS and ZunePhone2) will support HTML apps long before Tizen could possibly build any market share.
