oh, you are just using a simple future tense. im asking for future perfect tense not simple future tense but by the way, your answer is fine. i will consider it. thank you for answering but i already made one. thank you because even im already done in my assignment,you till answered 
i mean you still answered
The answer above is a future perfect tense form, it's correct.  If it's a just simple future tense, her/his answer could have been "April will win...", So April will have won... is correct :-)
