April 6th movement jumps for MB. How high is the next question.
Not high in the sense that they've attached a load of conditions, but very high in the sense that these conditions are unlikely to be tested until after the election, so in practical terms Im not sure there is much difference between this conditional support and unconditional support. All they've done is add slightly more pressure to the MB to form a broad and inclusive government after victory. But there was already plenty of pressure to do that, and the MB have not done much during or since the uprising to give people much faith they will go down this route.
April 6th's new stance appears to be based on the previous one. The previous plan, which earlier in June appeared to be backed by various protest movements and 3rd, 4th & 7th place candidates Sabbahi (neo-nasserist), Fattouh (ex-MB) and Ali (lawyer-activist), called for Shafiq to be disqualified, and for serious consideration to be given to having an unelected presidential council to take charge while some stuff is sorted out (such as the constitution). The makeup of this presidential council was along the lines of being comprised of Sabbahi, Fattouh, Ali & ElBaradei.
I believe the court verdict on Shafiq is due on Thursday, and I doubt that much hope exists that the verdict will eliminate Shafiq. There is another matter being considered at the same time that could result in the dissolution of parliament.
So the April 6th new stance is to back Morsi (MB), and to hope that upon winning he leaves his party post, appoints Sabbahi & Fattouh as vice-presidents, and ElBaradei as prime minister.
Sabbahi has been getting along especially badly with the MB as far as public statements go, and seems to have deliberately kept distance from them up to this point. Its rather unclear whether he will hop onboard after the vote, or stay out of power and concentrate on further building a movement. A story even went around that he had met Shafiq, but I think this has been denied and certainly doesn't fit well with his attempts to be seen as genuinely in tune with the aims of the revolution.
I see that the Tunisian Ennahda movement founder has been to Egypt to talk to various parties, attempting to promote the coalition/unity approach to power and constitution-writing:

Ex-contender Hamdeen Sabahi denounced what he called an organised campaign against him and the rumours spread by the Muslim Brotherhood and Mohamed Mursi's campaign.
During a meeting with Sheikh Rachid Al-Ghannouchi, founder of Ennahda Movement in Tunisia, Sabahi stated he will not support Mursi or Ahmed Shafiq in the imminent runoff.
Sabahi praised the Tunisian revolution and especially Ennahda Movement for not seeking to monopolize power after the revolution.
Al-Ghannouchi stressed the importance of Islamic national cooperation, stressing that both Tunisia and Egypt need a coalition ruling where power is not in the hands of one person or party.
Sabahi welcomed a Tunisian delegation headed by Al-Ghannouchi at his campaign headquarters to discuss the status quo in Egypt and the future of the revolution in light of the runoff between Mursi and Shafiq.
