I think their point is they did this in the laziest way. MGS2 and MGS3 are just the HD collection ports they made back in 2012 with maybe some bug fixes. MGS 1 the thing they were working on only goes up to "1080p" with 4:3 resolution. This is just a fundamentally worse collection that is meant to collect as much money as possible seeing as the Legacy collection was just a better package. They are clearly just going to sell a Master Collection Vol 2 with maybe MGS 4, peace walker, and the other ones ( a bit unfortunate we never see ports of portable ops, twin snakes (yes yes its just a worse 1 but I think its still a valid part of MGS history even though its the odd duck), and the MG acid games)
Edit: don't even get me started on some of the content that gets cut out due to licensing issues. We as players will never see Metal gear online 1, Snake vs Ape, and the guy savage stuff from MGS 3 alone. Hell there was also that pro skater mode for MGS 2 that never made it over with the hd collections.
