M2 is already aviable and possibly even M3. So it may not be quite so new. Anyway, reason behind all this is that FDF found out that BUKs reliability can't be quaranteed in all circumstances. There is no precise info about this, but there are some theories: 1) Russians left somekind of backdoor or other kind of vulnerability to the system (possibly unintentional). 2) This has something to do with that raid to Syria by IDF. 3)Then there are theories about how Georgian BUK:s were upgraded in Ukraine and were supprize to Russians when their ECM didn't have any effect. 4) Finnish army wanted to get rid off any Russian equipment, so they just invented this whole thing. IIRC around 2000 there was complaints from the army about how high maintainance BUK was.
This what is know in publicly: (Note! This standard Google translation from Finnish language news...)

Armed Forces Commander Juhani Kaskeala and Defense Minister Jyri Häkämies (IOC) have today, Wednesday, pre-care practiced a briefing, which describes one of the last decades, the largest single arms deals.
The army ordered a new air defense missile system, the new medium range of air surveillance radar system and update to long range of air surveillance radar system.
Total value of purchases for verges around 700 million euros, and the current economic crisis, the government must be prepared for the political laine would. The last major acquisition was the Air Force Hornets, who farms in the middle of the worst recession. The voters were tough, and sent the leaders of the opposition in elections.
Now the tasks of radar shops are part of the normal procurement cycle, when the technology is getting older and the equipment stops. Instead missile replacement is surprices outside experts.
Defense Forces' current-aircraft missile, a Russian Buk M-1 is still a relatively modern and, in principle, it should be the useful life remaining for many years. The missile was acquired at the mid-1990s that the payment arrangement in which Russia changed part of the Council during its debts to Finland. The gun is shown its abilities last in August 2008 in Georgia, the war, when it knocked down to the Russian aircraft.
Finnish magazine called Suomen Kuvalehti reported about a year ago that the Russian missile must be changed because it was the discovery of the enemy to go hole. Anonymous source from Defence staff confirmed information to the U.S. defense industry publication Defense News.
YLE news from various sources to the information available, at least according to their own policy-makers gave approval to the missile deal after obtaining military knowledge, that the Russian missile is vulnerable. Secrecy were married in a very small district the previous government.
Representatives of General Staff told verbally, and specifically Prime Minister Matti Vanhanen (Center Party) and Minister of Finance Eero Heinäluoma (SDP), the usefulness of Buk not be able to guarantee in all circumstances, the weapon is prone to outside influence. Due their position also Defense Minister Seppo Kääriäinen (Center) and President Tarja Halonen were adopted by resolution of the missile is replaced.
What is the external impact is, it is somewhat outside the impossibility to obtain more precise information. It is possible that today's briefing, even the defense minister does not permit to tell Buk problems, but the relevant issues must be forced to rotate. Outsiders do not want to give clues about where the "hole" lies, and the exchangeable missiles are still many years operational use.
A high-ranking source from Defence staff says without mention Buk that the problem may be, if the firearms to the range and extent of many users. International defense trade press has been some indication that Israel would be able to eliminate the Syrians used by the Russian air defense missiles, the two years ago in a military attack.
Finland took the missile deal pending, no later than three years ago. The acquisition of a public tender European arms agency, EDA's to maintain a register of attracting attention to midsummer, after June 26, 2006.

After that one interview coming out from the FAF major years ago, about what FAF actually wanted to do with them (or then also with Storm Shadow), I don't blame Yanks didn't want to sell them then.
