The EU on a way to federation

So it looks like France and Germany agreed for a new treaty change. Yet this time the logic of change is different. It is enough if some 17 plus countries ratify the new treaty for it to come into force. This looks like a situation experienced by the States of America when they were ratifying the US Constitution in 1787...
So this is a historical moment: change from a confederal rule of unanimity to a federal rule of a majority. Ok, a special majority where France and Germany have to be in, or do they?
So the next steps are as follows:
The European Council will agree this week to start the treaty amendment process. Then the European Parliament will use its right to convene a Convention, why should not it insist of this right?
So in March we start a Convention, which we probably be limited in time - let's say till end of July. The new IGC will be so locked by the Convention that it will barely touch on the substance and in December 2012 we shall start the ratification process. However this time ratifications will be clearly scheduled in a sensible way. Starting from the most pro-European to the least. So if the majority to enact the treaty is set at let's say 4/5 of the countries and 2/3 of the population we shall see an interesting count down.
Maybe it is time to undust my thesis on the dynamics of the Convention? Who knows....
Now let's see who will chair the next Convention? Is it Mr Van Rompuy or the Convention will be allowed to choose itself? Rather not.
