Will it be possible to buy that deluxe/collector's edition thing or whatever it's called when hl's definitive edition comes out? (more important info is below about my question here)

i got the regular version of hl when it released rather than deluxe or collector's and bought the dark arts pack later on and i like it but i think i need deluxe/collector's to get the kelpie robe...
