It depends if Intel decide to base their prices of the RRP of competitors cards or the price they're actually selling at.
If they target RRPs of competitors cards then it's going to be a good day for gamers as Intel cards will have a price/performance advantage over Nvidia/AMD and gamers will actually be able to get them.
If they target the retail prices then it will be less good for gamers but at least they should be easier to obtain than their red/green counterparts.
The thing is by AMD/Nvidia essentially ignoring the sub £400 market for the most part,it only needs for Intel to have something not totally crap in the £100~£300 to get more share. To put it in context the best sub £300 GPU you can get easily now is a GTX1650 GDDR6 4GB or a GTX1650 Super 4GB.
