It would be nice and I think there are big chances for that, if you look at Spring Sale dates from years before.
It would be also nice to see come back of some old good sale ideas as deeply discounted bundles, bonuses for collected xp and/or even insomnia-model perhaps. On the other hand I'm afraid that they'll try make something special and choose mystery-game scheme or sth.

If I would be a sale manager, then I would make a Horde's Invasion Sale,
connected with releasing of Warcraft 1 and 2 starring as main cast.
I would suggest to delay it until April. The hunger of Big Sale would be bigger then ;)

What I'm seeing from OP is that they never, ever fail to do a sale in March and since we've already passed St. Patrick's, a spring sale should be imminent. Though I guess it could be next week.

Who knows? Perhaps - point for you :) Check the link.
Spring Sale is coming?

According to the image from that newsletter, it seems the blues have read my previous post here about Horde's Invasion. Kek.
I don't wanna be like Sapkowski, but where is my profit? ;) Just kidding.

4 hours and we'll know!

I'd really like to see a big sale before a summer one, but we've had one every month so far this year...
C'mon Wizardry 8 plz

hope baldur's gate 2 will be on sale soon :)

Here :)

So it's safe to assume that the summer sale will start first week or so in June huh?

Nah, they changed their minds. Gotta wait for the Christmas sale.

Lol ;)

Apparently Steam's summer sale this year will start from June 21st.
If GOG keeps their trend of having their summer sales two weeks ahead of Steam's, we should see our sale start from the 7th. A little over three weeks from now.

Start savin yer dough folks!

e: the two weeks before thing is not totally accurate as I've just checked, but for the past three years it had been two weeks before. In any case, GOG has always held their sale BEFORE Steam's.

From your source, Polygon claims the 21st, while RockPaperShotgun's article says 25th. Either way mid July, plus or minus a week, we can expect GOG's summer sale.

EDIT: Actually they are both citing the same source, but RPS's article links to a more recent tweet, so it might be that the 25th is the new sale start.

GOG is screwed. Epic just started their month-long sale, with discounts + an extra $10 off every purchase above $15. GOG is going to be sandwiched between sales. This is a huge blow to GOG, unfortunately.
