1280x720 with graphics on maximum ugly is not entry level. Its console level. You'd think that if you want to game you'd game on a gaming system not weak iGPU's.
Don't you think it's a bit pointless jumping into a thread intended to discuss possibilities for the future Mini's graphics &, in turn, its gaming potential, with a reductionist dismissal tantamount to: don't bother, just get a PC!
I see your argument in favour of 2 dedicated systems if doing serious work in OS X, yet gaming is a priority. I've gone that route even though gaming
isn't a priority (due to limits on my free time).
However, for many Mac users, whilst far from a priority, gaming is still an enjoyable interest.
Yes, they could buy consoles. But many games either just don't work too well on consoles, or aren't even available, for eg., RTS games like Total War.
Thankfully, gaming on recent Minis is more than viable. My 2011 Mini with HD 6630M discrete video is no slouch, despite being hindered by Apple's stingy 256 VRAM. The weaker HD4000 in the 2012 Mini, whilst not discrete, can optimize up to 768 VRAM (if you've 8GB RAM) & plays many modern games acceptably at medium settings & higher.
Haswell chipsets are stated as having up to
3 times the graphical power of Ivy Bridge. I'm not convinced that's what will end up inside the next generation of Minis, instead of something compromised. But if I'm wrong, IMO, that'll be an impressive leap forward in the Mini's graphical capability.
No-one expects a Mini to compete with current, dedicated gaming machines. However, for those who need OS X, find that the Mini is powerful enough for all their serious work & don't want a PC, then gaming either in OS X or in Windows via Bootcamp (& often getting better FPS) seems a reasonable option, be it with inevitable compromises.
