FIDE President's Race - Is it four or two candidates?

A new candidate has thrown his hat into the race for the FIDE Presidency, with Arkady Dvorkovich becoming the fourth candidate for the office. The details of his announcement can be found in this article on chess.com, including some discussion about what this means for the other candidates.
One theory is that Ilyumzhinov will now drop out of the race, as the Russian government will shift their support to Dvorkovich. Taking it one step further is the suggestion that the Makro ticket will merge with the Dvorkovich ticket, with Dvorkovich becoming the Presidential Candidate, Makro remaining as Deputy, and Malcolm Pein being let go (or offered a Vice President position as a consolation prize).
However I'm not sure that the second scenario is as likely as the first, as the logical step for both parties would have been to negotiate this behind close doors. By announcing his candidacy in this way Dvorkovich seems more likely to have his own set of office bearers in mind (although defections from the Makro ticket cannot be ruled out)
Nonetheless, a new Russian candidate wouldn't be seen as bad news for FIDE insiders. The real problem that the current FIDE executive have with Kirsan had nothing to do with his management style, or ethical issues, but simply that he is now costing them money. While he was bringing money into FIDE (through personal contributions, or connections with other governments) concerns about his ethical standards were dismissed as pro Kok/Karpov/Kasparov propaganda, but when FIDE had to actually pay for his expenses (and there was less money for pet projects of other board members) then suddenly the other issues that had been ignored for years became critical to how FIDE 'should' be run.
So if Dvorkovich can bring in a new income stream (or just resurrect Kirsan's old network) then it can be business as usual in the Athen's office.
