They have already spent millions of $ for the new system. I doubt they'll make a new one. Their first choice would be to improve the infrastructure. All they need is more & capable servers.
Besides, I'm pretty sure based on the agreement between MIDI & CGI firm they have to resurrect services asap otherwise they'll face serious fine. What feels like a joke is that more than a week later there's still nothing announced.
My guess is that they're planning to reopen with added capacity in beginning of March, but they'll not issue a statement beforehand; just the date&hour on webpage 24 hours ago. If things are seriously gone out of hand (which I doubt) they'll cancel this intake and make a huge one time intake on summer with a completely overhauled system.
