Haven't heard back from Imperial College London after the interview for MRes Catalysis

[SB]

I have applied for the MRes-Catalysis course at Imperial College London. The interview went well. He was "impressed" and "promised to put in a very positive review for me in his report to the Registry". But, it has been almost 2 weeks and I haven't heard from them, although he said that they may contact me in a week. Can someone please help letting me know how much time does Imperial usually take to reply? Also, since he ended the interview at such an optimistic note, is it safe to say that I may get in? You help and guidance would be much appreciated!

He told me the exact words! I just finished my interview. 

What happened after that? Did you make it in?
