Based on the current general counts, Trump is only about 70 delegates away from the 1237 mark, and there are just over 300 delegates in the remaining primaries.
It does look like he will surpass the 1237 mark by a hundred or more.
From GreenPapers:
Trump Soft total 1168.
There are 347 left!
My guess is 1411 or 1414.
Ted = 666
Glen will slit his own throat.
